Deformaties resulting from inbreeding.

There are many causes for Splaying of the legs. Some have said it is due to
deficiencies in the diet. From my experiences, it happens more when it's
cold. The hen sits too hard on the chick causing it's legs to splay.
Typically the legs are splayed back with no bend to the joint. Single and
dual spaying are also possible. There are other factors also associated,
but it happens, hopefully not too often.

There are ways to correct the splaying, if caught early enough, but it's not
guarantied to work all the time. You can search or ask an exhibition
breeder. Let me know if you need further explanation.

Typically brother to sister inbreeding causes smaller birds in Exhibition
budgies or sometimes feather dusters (a form of down syndrome in budgies).
Splaying may not always be a direct result of such pairings. Most
Exhibition breeders will pair Son/Mother, Father/Daughter,
Half-Brother/Sister, Uncle/niece, etc., that is called Line breeding. The
key is not to pair identical genes, like Brother/Sister. Half of the genes
must be different, even if it's only 1/4 of the whole.
