I have a rooster who has wasted down to nothing (Marek's). He got a bumblefoot and I opened up the scab and could not find anything. I put a small slit in the top between his toes because it was so swollen that I thought maybe there's a kernel in there. He's still limping. I can't take the bandage off because he will bleed a lot. He's probably low on clotting factor. Antibiotics don't seem to be working. I'm having a problem throwing in the towel because I will feel guilty I didn't do enough. It's a sad situation . I could give him Penicillin injections but he has no fat at all. He's still bright eyed and eats small amounts. Where do I go from here?
