Any minute now, they'll be bigger than I am. I put up an outdoor roost using a 2x3 and it bent so badly in the middle that I'm pretty sure it will break soon from their body weight - and only one uses it at a time. When they fly off of it, I run away because their wing spans are so great. I'm not the only one who flees either. One of my dogs was looking for a place to do her business yesterday and ran up to the turkey enclosure. All three of them took flight and now my dog is traumatized for life. I think she thought she was being attacked by dinosaurs. How big can they get? We're looking at another two months before butchering them and I'm pretty sure that they've topped 20 lbs a pop already!
