rooster will not sing

[DementedHam]

my aunt called me no to long ago telling me that her rooster has stopped singing. this is one of the "symptoms" that has accompanied what she says is a sort of depression her rooster has. The rest of her flock is all well, he has no injuries she has seen, he walks around but kind of sad-like. any ideas what it might be and how to fix it. this has been going on for a bit over a week so she is a little worried. the rooster is a 1 year old white leghorn.

thank you.

We need a lot more info. What he's been eating, has his weight changed, has he been checked for worms, is there other roosters around, what changes have occured in his physical appearance, changes in stools, and other behaviors. Good luck.
