what is up with that? i have two coops, they lay in the one coop more than the other but both buildings do see action. i have 7 hens and one rooster. instead of them going inside they roost on top of the roof! its getting to be winter here and im afraid they will freeze! what can i do? i put a very small heat lamp in one coop and left the other one alone but they still roost on the roof? it freezed rain here the other night and the hens did go inside but bless my Big Red rooster he stayed perched on the roof! what am i doing wrong? i want them to be comft and safe?
