I have a flock of 5, one each gold laced cochin, RIR, and Dominique and 2 Crele old English game bantams. My 2 OEGs have taken to roosting on top of the coop at night instead of going inside. Nights here are bordering on freezing so should I worry? They are inside the run so still pretty secure but we are just starting winter and it looks like its going to be a really wet one so wondering if I need to worry about them getting sick.
