Does anyone else have this problem? Our girls have 3 very nice roosting bars, ample space for the 14 girls. Yet, they all seem to risk their lives nightly to sleep on the roof rafters. Getting up and down seems to be quite laborious for them...I'm afraid they'll get hurt. We've had a few fall from the rafters, in the summer I don't use shavings in their coop, just a linoleum floor with a dusting of powdered PDZ. Comments are welcome!
