We have some laying chickens and have had for a while. I have a neighbor that has 7 midget white turkeys and she is nearing retirement and wants to get rid of all of them before a spring vacation. 3 of them are 3 years old and hatched out 4 babies last October. I assume the standard butcher time is 22 weeks give or take a few?? What about the older birds, I, again, assume turkeys are like chickens and that old will only be good for soup if butchered?? She is willing to get rid of all 7 for $100, seems like a great deal. Also, do i need to cover the top of the run for turkeys? Can i clip their wings? I don't cover our chickens run...Your thoughts?
