Hello this is in follow up to yesterday post regarding emaciated chicken not eating. Went to avain vet today. All test turned up fine. Suspected internal cancer that was not visbile via xray and put to rest as to not suffer. Vet will do the necropsy. My question is could there be environmental explanation for cancer in birds? I lost two others over year ago to cancer all from different breeds and breeders and ages..I find it odd to have 3 in 3 years die due to cancer.
