Hi, my chicken is coughing and sneezing. he has been wheezing after he crows for about 1 week and a half. he has recently survived near death after he had extreme heat exhaustion twice, i don't know if his wheezing and sneezing has anything to do with this? i have read that we should feed him scrambled eggs and bread covered in olive oil, however he doesn't seem to want to eat the bread. we have just bought 2 new hens for him (as the others died of heat exhaustion) we don't know weather to separate him from them as we don't know if it can spread. Also does anyone know the best way to get rid of mites? thank-you!
