I have lost 4 roos in 6 yrs. I have 2 hens that I have had for 6 yrs and they are healthy. I just lost my 5yr old Bantam Brahma roo. I took him to the vet and did an x-ray-he had a very large mass in his abdomen. His symptoms were not passing stool, diff breathing. This mass was obstructing his GI tract and his breathing. How long have you all had your roosters?
