I recently got my little flock of 12 chicks. They are almost 3 weeks old and are living in the garage. We will soon be building their outside home. The run will be up against the house. I am worried about predators since I don't know that much about them. I am in suburban Maryland, so no big scary predators. Is there anything that we should be aware of in terms of predators getting in where the run meets up with the house. Anyone build a run up against their house? Thanks!
