I have 2 10 week old BBB poults that are now in the big turkey coop that we just built for them. They were in a large cage but started attacking my hand when I would feed and water them. They have been in the new big coop for almost 2 weeks now and still will chase you when you go in and get the waterer to refill. I want to start maybe to let them free range during the day but is 10 weeks too late to start free ranging. I am afraid they will fly off or run away. I started free ranging my 5 week old poults yesterday with my 5 week old chicks but I put them back up after a few hours. I am afraid with the BBB being bigger birds I will have a time chasing after them as they aren't the "friendliest" birds.
