So I have 6 hens and a rooster, they've been in their new coop about a week. They will get on the roost (1 is 15 inches off the ground and ~8ft long, the other is 30 and 8ft long) but at night they tend to literally form a ball in the corner of the coop... I'm not "too" worried about it but I figured they'd rather be roosting... Anything I'm missing? Thanks.
