I was surprised to see my little underweight crossbeak mount her best friend the larger white EE. She even grabbed her neck. When I looked at my larger hen later I saw a dark mark on her lower back where I could see she has been pecked quite a bit. I put no-pick stuff on it but I'm wondering who did the pecking and if it's because they have been locked up in the coop and run since the time change. Is the mounting behaviour connected? The crossbeak girl has never been dominant and is not sexually mature like the other 6 month olds. They have 47 sq ft for the 5 of them. I was hoping that would be enough. Do they need more room already? Gonna be a long winter. Thank-you!
