2 weeks ago I noticed my 5 month cockerel is not eating and comb is droping, turning a pink/ white color. I asked a few people. they had told me worn, vitamins and maybe heat exhortion. so, it been 2 week. I've used safe-guard and wazine wormer, nutri-drench and durvet vita and electrolytes, probiotic, apple cidar viniger, garic, and antibiotic. I change his food and put him in a cool area. I check his crop thoughout the day to see if he is eating and it has a little liquid in it. I've tryed everything that people tell me, still no change. this is a picture of him 2 weeks ago his comb is now like a white spoted pink with a few scabs on it. If anyone knows whatis wrong with him I would appeciate their input. I'll try to get a more recent picture. thanks
