We have a three-four year old BO rooster who has problems with the preen gland on his tail. It does not seem to be infected, just full of preening (oil?). He is very sensitive about his tail, including tail feathers and especially pin feathers on his tail. I tried to squeeze the gland to get some of the stuff out, and some of it did come out, making the gland a little smaller. There was no color or anything out of the ordinary. Our rooster does have an oddly shaped beak. He lost the top quarter-inch of his beak in a cock-fight about three years ago. It has not affected him much, he keeps himself clean and he can look after himself without any difficulty. However, I'm wondering if maybe his beak has affected his being able to reach the tail preen gland. Is there anything I can do to help him? Thanks!
