Splayed Legs

Splayed Legs
By Dr Hamish Baron Bvsc (Hons) FANZCVS (Avian Medicine and Surgery)

There are two types of splayed legs in budgerigars, the first is a congenital form (acquired before birth) where the chick hatches with mal-positioned legs, having been sitting in the egg in the wrong position. These chicks are unlikely to improve without immediate intervention, and even then, their prognosis is poor. The second type of splayed legs is an acquired form – this is the one that we can prevent (and treat) through better husbandry and management.

Acquired splayed legs are the result of several factors, but the end product is a chick whose legs sit in an abnormal position, either splayed out both sides like an airplane’s wings or both splayed to the same side, so one leg tucks under the baby’s body. Both forms of splayed legs run the risk of further complications – the longer the baby’s legs are splayed, the higher the possibility that the baby will develop hip luxation. Hip luxation is where the head of the femur pops out of the pelvic socket and the result is a bird whose legs will never be normal. Therefore, it is critical to correct these babies as early as possible.

The Causes

So, what causes splayed legs? As I said, it is often something that we are doing wrong. The most common cause is an incorrect diet that does not meet the metabolic requirements of the parents and, therefore, the babies. Most often it is attributed to a low calcium level in the diet, but it can also be related to protein levels and any other mineral required for correct bone formation. It is for this reason that feeding a complete diet long before the breeding season starts is so important. It is not suitable to start supplementing calcium and soft foods when we pair the birds up, or when the chicks hatch – the fact of the matter is, the nutrition that the hens are able to put into the yolk comes from the diet we feed long before they lay their eggs. Having yolks full of nutrients and energy is going to help with hatchability, as well as having healthy chicks in the nest box.

Hens that sit too tightly early on is something that we can address easily by either placing a block of wood at the edge of our concave or by placing a 20mm marble in the nest which does not allow the chicks to be squashed. Leaving un-hatched eggs in the nest allows newly hatched babies to have something to lean on and will also keep the hen from sitting too tightly. These do, however, end up getting very dirty and should be removed once the chicks are about 10 days old.

Lastly, the easiest way to avoid producing chicks with splayed legs is to have the correct substrate in our nest boxes. Every week I deal with breeders who got tired of refilling the nest with substrate after the hen had cleaned the box out – this is no excuse. Raising chicks on a wooden nest box floor is asking for trouble. Having done all the hard work to pair birds and to have had the eggs hatch, there is no excuse for not having substrate in the nest box. Most hens will forget about cleaning out the substrate once she has laid her first egg. We use pine wood shavings; I know of others who use coconut husks and peat. It is a matter of finding the substrate that works for you and providing it for the chicks to have something to grip on when they are moving around the nest.

Early Detection

If a chick of yours does develop splayed legs, if it is detected early enough it is easy to fix by placing a splint on their legs. There are various methods you can use but the most common is to use soft foam. I like the soft foam method but do find that sometimes the holes become too tight for the growing chick’s legs. An alternative to this is a pipe cleaner or wool tied between the chick’s legs.

Many breeders utilise their society rings and put a ring on either leg, this allows the legs to be tied together using a pipe cleaner, wool or string without risking making the loops too tight – it is a good idea if you have spare rings!

To repair splayed legs, it is best if the chick is on its back and there are two people as it makes it easier to bind the legs together.

Firstly, wrap the pipe cleaner around one leg just above the ankle and twist the pipe cleaner to make a loop around the ankle, not too tight but not loose enough for the chick to slip its foot out. Then put the legs together to just less than the normal standing position and wrap the pipe cleaner around the other leg making another loop around the ankle, making sure to cut off any excess pipe cleaner.

The splint will need to be left on for anything from a few days or up to three weeks depending on severity and the age of the chick. Remove the splint every few days to see if the chick can walk. If it is ok then leave the splint off and keep an eye on the chick’s progress, but if the legs are still splayed then replace the splint.

If splayed legs are not treated early enough then the chick will remain abnormal for the rest of its life. As the chick grows older and develops, its bones calcify, meaning that the bones will have hardened and are no longer soft and pliable and therefore cannot be corrected, so any correction must be done before the chick is two weeks old. Longer, and the treatment is much more complicated and the outcomes less favorable. Although chicks survive and do learn to adapt (with our help) with one splayed leg, having two splayed legs is difficult as it will never perch normally and end up placing a lot of pressure on its internal organs causing pressure sores and illness.

In summary, a great diet, good planning and an attentive breeder means that we can work to make splayed legs a thing of the past – it is a condition which we have the ability as breeders to manage out of our studs and I implore you to take up the challenge next season to try and produce round after round of healthy chicks by providing your adult birds all they need during the off season to produce great youngsters for you during the breeding season.

Night Fright

Night fright occurs after our birds have roosted for the night and something causes them to panic. Causes can be car head lights, cats, rodents. If this is likely in your location a low wattage night light is recommended.


Too low or too high humidity is not usually an issue in the UK. In the birdroom to increase humidity you can mop the floor with water.


In the wild, budgerigars live in flocks of hundreds or even thousands of birds. Birds within the flock will fight to establish the social hierarchy (pecking order). This same instinct appears when too many birds are kept together. Hens are usually more territorial than cocks.

The preferred perching for budgerigars will be that which is higher up – challenges to sit up high can cause fights. However, budgerigars are rarely aggressive by nature and outbursts will end quickly.

Feeding Problems

Sometimes the first chick may not have been fed, especially if the hen has not reared chicks before. If this should happen, try removing the chick and replace it with an older one. The extra insistence to be fed from the older chick will often stimulate the hen to feed.

Feather Plucking

Feather plucking is one of those frustrating problems that occur from time to time in the birdroom. There are several causes raging from an inherited behaviorism to boredom.

Most often it is the hen but can be the cock. If feather plucking occurs in a nest and it is the cock then remove him and leave the hen to do the work of bringing up the chicks.

However, prevention is better than cure and as feather plucking appears to be more prevalent in smaller clutches of chicks it is worthwhile transferring chicks from other nests, so that the small-numbered nests are brought up to four or five chicks per nest. Do this by removing one chick from, say, two or three larger nests. This method works because the hen is too busy feeding a full nest box to allow boredom to kick in.

Other methods of relieving boredom include leaving a radio on all day. Budgerigars definitely like the noise, as when it switches off at night all will go quiet, and the activity will diminish.

Another thing that can be done to help alleviate feather plucking is to put a piece of millet spray into the nest box; this will often distract the hen away from her chicks as a relief from boredom.

Feather Dusters

Feather duster budgerigars sometimes called mops, are budgerigars that have a genetic condition characterised by overly long feathers that do not stop growing, giving the bird the appearance of a feather duster. This condition is sometimes known as chrysanthemum feathering. The feathers do not have the necessary barbs and barbules for the feather’s structure to interlock. The feather shaft is also curved, and so the feathers appear deformed and fluffed out. Individuals with this condition often appear less alert than nest mates.

They lack vigour, often cannot fly, and usually die within a year of hatching. There is no treatment.

Egg Binding

Egg binding is when the passing of the egg through the reproductive tract is delayed. It is a life-threatening condition and so it is important for egg-bound hens to receive prompt veterinary treatment.

The symptoms are:

  • Rapid or labored breathing
  • Swelling
  • Constipation
  • Fluffed-up feathers
  • Straining
  • Sitting on the cage floor
  • Drooping of the wings
  • Lameness
  • Loss of appetite

Insufficient calcium can be one of the causes as well as a lack of maturity

Dead In Shell

Dead in shell is when the young chick (embryo) dies from the 16th day onwards. This is caused by a failure to hatch for several possible reasons including dehydration, weakness and deformity.
