Hi, We killed and cleaned our two turkeys today. Both had very gassy intestines and each had a few yellow masses inside the cavity, not attached to anything. I have never seen this before. The birds were about 4 months old and free ranged, fed organically. We had put their poult-mates down months ago due to respiratory problems that developed after using wood chips in the brooder -- but these two seemed to recover. The chickens they lived with never had so much as a cough (and were unremarkable when I butchered them). So stiff, yellow, flat cheesy things in a cavity, about the size of a 50 cent piece. I thought is looked fatty. Any ideas?
