I am a new owner of three month old bard rocks and Rhode Island reds. They live in an enclosed area of about l5x30 feet with coop we use at night. That's the question. Of late, they take to the lilac bush to roost rather than their pen. I am wondering if they are safe there from say owls or hawks? It's not hard to lift them out of the tree and put them into the pen but is it necessary. The pen and enclosure is close to the back of the house. thanks from Grandmaruth and grandpajay.
