I had to put down a turkey last week, thought perhaps her heart was failing (Happened last year to two of my BBB's, so I figured early butchering was the solution if they showed lethargy), but it was much worse, because i could not use the meat on this bird. Notice the yellow lesions. Blackhead, no doubt. The green color, I have been told by the extension agent, was probably due to staph or E-coli infection secondary to the blackhead. there is no treatment except the Flagyl, as some here have suggested, but the agent said i could never eat the meat. I looked up natural alternatives, and found that cayenne pepper and ginger are helpful. I checked out my theory with a veterinary patholigist at church, and he said that those are great ideas, and had shown some success when they were studied by poultry researchers in Georgia. The remainging turkeys are improving. I give them cayenne, ginger, lots of probiotics, diatomaceous earth to cut down on cecal worms, and most of all, I penned them up in a paddock where goats had been but chickens had not been. I am keeping my fingers crossed. They are starting to run to us again at feeding time, and are more vocal and active.
