My silkie rooster had a bad case of mites in his crest. I bathed and sprayed with Adams flea and tic. The mites are gone but he has been very listless. He is sitting all of the time and is losing weight. No crowing. He doesn't leave the coop. this has been going on for over 2 weeks. I just moved him inside the house where its warmer and have started an antibiotic in the water and also vit. and electroliytes in the water. Is there any thing else I should be doing? I don't want to lose him!!!!!!
