I have a 2 acre yard fenced 6 ft. high. I raise chickens and turkeys. I've raised the BBB without any issues, but I want to raise a heritage breed. I like the Bourbon Red but I have some concerns that they may fly out. My BBB turkeys were very content and never tried to leave. I'm just wondering if I need to take extra precaution for the Reds, or maybe just stick to the fat boys. Let me know what yall think
