I know this is a chicken site... but I recently got this donkey and I have a few questions. I was hoping someone might be able to help me. The previous owner said he got some kind of shot in both sides of his mane on the to of his neck, they said it was to help "calm him" . Since then he has developed these very large pockets of fat on his neck. The donkey also has one eye that constantly drains. I would appreciate any advice.
