Hi, I have 2 Australorps and 1 Sussex. They are doing very well and are my first chickens ever! The Australorps are about 2 months old with the Sussex being around 3 months. They are very friendly and love cuddling together during the day in the dirt or wherever they want. They have lots of room in the coop and send themselves to bed with me locking them up right after. Whenever I come to lock them up the two Australorps are in the nesting box with the Sussex roosting on one of the bars. There are about 3 roosting bars so they have lots of options but the Sussex always pecks at them when they try to roost with her. Is this bad and if so how do I fix this and help the Australorps to roost?
