Hello. We are returning to chicken keeping after 25+ years. We have 5 hens right now, and one Rooster. 3 Rhode Island Reds and 2 Barred Rocks. The Rooster is a Barred Rock. One of the RI reds has been hiding in the coop. They are 5 months old. When I picked up the lone hen, she drooled. I isolated her for one night, and she perked up. I put her back in the coop, and she's hiding again. Could the rooster be picking on her and stressing her?
