I have 7 Buff left, started with 11 in an 8x8 floor space and 6 tall, 3 nest boxes. I had 1 fly out of yard and get killed by a dog last Nov. We had a stray climb the fence about 3 weeks ago and kill 3. So now I have 6 hen and 1 rooster in the same area. The 11 were just as happy as the 7 are. They have plenty of room but still roost close together. I added 2 more nest boxes to give more room but none will use them, they all crowd into the 3 boxes.
