Looking for answers. This is my first attempt at raising turkeys for food. As a recent cancer survivor, I have become very particular about each organically and as pure as possible. I purchased 12 white broadbreasted turkeys June 1. I demanded that they not be vaccinated as I plan on harvesting them for meat. I lost 5 for various reasons, 3 to illness and 2 to predators. The remaining 7 have been thriving until this week. One Tom is looking very sickly. He sits all the time even when turned out on pasture. He was looking a little shakey in the legs but he was/is still eating. Tonight I noticed that his head and neck are changing color from a healthy pink color to a blotchy red. My questions are: Is there anything I can do to bring him back to optimum health. Does anyone know what might be wrong with him? And if I must slaughter him early, is he safe to consume? They all get a diet of corn and oats (unfortunately I am not sure if it is non-gmo corn nor is it organic). They also get organic sunflower seeds and turned out on pasture for several hours per day. Would do more but the foxes and hawks always hang out here. Fresh water daily. I don't know what else to do.
