I have an A frame roof on my run, Yesterday afternoon, I heard the girls just going bonkers, I run over and there is a hawk sitting on the top of the roof, the girls were under their coop by then, so I just threw a stick at it and it flew off. The top is hardware cloth, or chcken wire covered with a tarp. Last night I got home and there is an owl sitting in the same spot. I KNOW the girls are safe, but any ideas on how to discorage them? I had actually shut the girls in their coop, because I was nervous.
