I have two female white BB turkey's that are 21 weeks old and about 10 days ago they started to show symptoms of Blackhead disease (just figured this out yesterday), there is also a Tom that is showing possible symptoms. They are scheduled to be butchered in 10 days. They are all eating and drinking a little though one has not walked for over a week (but can stand on own). My question is whether I should be culling these three and discarding their carcass' or should I butcher them with the rest and eat as normal? My other concern is should I try and get them butchered earlier so the other 7 don't get sick? Any help would be greatly appreciated.
