It is not really known why
this happens, but it is assumed that at least in the majority
of cases it is probably genetic and so it is recommended that
no breeding is done with a chicken that has a crooked/crossed
beak.
As long as the chicken seems
quite happy, and can still eat and drink ok, then it is usually
not too much to worry about - chickens with crooked beaks can
lead an otherwise 'normal' life doing all the chicken things you
would expect them to do.
If it does seem to cause a
problem with eating, then a mash instead of pellets may make it
a bit easier. Raising the food off the ground and/or a deeper
dish can also help those with beak troubles.
A lot of cases of crooked /
crossed beaks can be improved by trimming. Trimming is usually
best done by a vet, at least the first time (beaks are like nails
and it may need to be done every few weeks). Parrots and other
'pet' birds sometimes need it doing aswell, so vets do see the
issue from time to time.
