As a new owner, I'd love some insight from you more experience keepers... I don't get the impression that my birds are totally dumb, but.. some of my birds, which are all between 7 and 10 weeks tend to nest down under the coop, on the ground. They're well hidden, and sheltered from the wind, but there's a nice coop right above them. Why would they pile upon one another outside when they can sleep inside where it's warm and there's food and water? I put a few of them up the ramp to the first level of the coop where they immediately ate and drank... Thoughts? Am I too worrysome? Thanks!
