I tried to tell my girls that they shouldn't huddle so close together.... There are 4 more roosts other than the top, but all 8 cram themselves up on the top only a little over 4 foot across! And these are full-sized birds! What's really funny is that the face different directions sometimes!Each grown bird needs at least 18" of space on the roosts.This is for large fowl. You might get by with 12-14" for bantams, bearing in mind that they tend to scrap more.Chickens are not missles. They need room to spread their wings to get on the roosts!
