I got him last Thursday as a auction save. He's weezy, he has mucus I guess you would call it, coming from his mouth. I have him some wormer, he's been getting vetrx by his nostrils. He seemed to be eating more this morning. But also had drool hanging out of his mouth. He's being kept seperarated in a XL dog crate right now. He doesn't seem as lethargic as he did when I brought him home. But I'm still concerned. Can I try to give penicillin? If so, how much? And where do I inject in a chicken? Or does anyone have any idea of what could be going on? Or what else I can do?
