I am new to chickens and have a mixed flock. I have a 1 year old red sex link hen and 3 almost 4 month old Wyandotte mixes in one coop. Red is a bit of a bully. Shes the sweetest, most docile hen with me. She hasn't caused any injuries but she terrorizes the other poor hens around the coop and run. I've been allowing Red to free range for part of the day so the other hens get some peace. I also have 3 4 week old hens that I was planning to build a small coop for. I wonder if I shouldn't just separate Red in her own coop while I'm at it.
