Ok, I have just completed a new 6ft x 8ft coop for my 8 girls and 1 rooster. Inside the coop there are 2 roosting poles; one approx 5 ft off the ground and 6 ft long the other is approx 3 1/2 ft off the ground and 3 ft long. My chickens are all in the coop every night, but, they are huddled together on the floor. I live in NW Georgia and the weather has been cool, but certainly far from "cold". The roosting poles are 1 1/4" PVC, screwed in so they wont roll around. Any idea why they are chosing the ground over the roost? Maybe they didn't use a roost at the hatchery where I bought them....they are about 6 months old...all Buff Orps, and all CAN fly. Any thoughts? Should I be concerned? Thanks
