My rooster quit crowing a few days ago and he keeps to himself. He stands kinda hunched up with head pulled in. He has quit crowing and stays to himself. My husband and I checked him last night on the roost and he has a bump on his chest on one side that you can put your fingers around about the size of a golfball. You can feel something in there. Sooo, I have seen the video on here where the lady actually operated on her chicken and cut it open and took the stuff out and sewed it back up. I am leaning that way if I can get what I need from my vet---any suggestions???
