I got my three Buff Orpingtons as chicks in October. They just moved outside into their coop a couple weeks ago. The last 2 days have been the first really sunny ones since they've gone outside. I thought they would be excited and more active. But it seems like half the time they are just sitting inside their coop (not even walking around in their run!) Is this normal? Or is there something wrong? Also, what should the floor of their run look like? I threw some straw on it but then how do I maintain it? Could the floor be affecting their behavior in this way? Thanks for any input!
