Recently we took out the old roosts we had in the coop and replaced them with multi-leveled, much wider ones, which made our girls pretty happy. Since this change I've noticed that my SLW Bertie has, funny enough, been sleeping with her entire head under my Salmon Faverolle's body. They have always been roost buddies, always sitting together, but, uh...why this? When I go out after dark to check on everyone, Bertie will emerge from the depths of the other chicken to say hi, often panting a little with her wings spread. Should I be doing something about this? I mean, it kind of cracks me up, but at the same time Bertie seems really hot. But she goes right back to it when I go to leave. Becky the Salmon Faverolle doesn't mind a bit. She'll even have a wing out sometimes. Chickens are so strange. Please let me know if this is unusual or something to be concerned about.
