My girls (6 of them, all RIR's) are about a year old now and have been very healthy. They are eating, drinking and pooping normally but don't seem to be roosting at night... they were all huddled in a corner last night (They aren't cold, I'm in Fl and it was like 70-something last night)... They are laying well, same as usual, no changes. We DO have new neighbors that keep their backyard flood lights on all night, but would that cause this? What could cause this? Is this normal? Should I be concerned? We checked their feathers for mites or anything of that sort and didn't see anything. Help please and thank you?!?!
