Hi there, My 4 new hens have taken to roosting on top of the coop rather than inside. They are presumed safe up there since the coop is surrounded by a very secure wire enclosure, so I'm leaning towards letting them continue to roost there. However, I wonder if it's ok for their feet to perch on the peak of the coop on asphalt shingles? The other questions I have read about this only gave suggestions about how to get them back into the coop. Any advice or suggestions would be great. Thank you!
