I have a rooster that seems to be in good health. Good body weight and he eats well. The problem he has a cheezy build up around his vent . It stays moist Iscrape it off causing it to bleed. I put anti -biotics on it but it seems to grow there. IT does'nt seem to bother him at all. I know its not normal and I am worried about it. I need someone to help me on this. Please anyone ever have tihis let me know what I can do about it . Thank you.
