Few questions about turkeys. I had some for a 4h project many years ago. I raised them in an aviary and moved them outside when they were about 7 or 8 pounds each. Only problem was they preceded to stick their heads through the chain link fence and get them bitten off by our dogs. Needless to say I don't want that to happen again. Currently, I have a fenced yard where I can house them, approx 30' x 30'. I will be building a "coop" for them to go into at night before I get them. So... Questions; # 1- are they going to stick their heads out of the chain link fence and die like the other ones did? What could I do to keep them from doing that? #2- What is a good turkey for a sustainable flock, raising themselves etc... #3- What age birds should I get? Thanks!
