I have 5 chickens that are in a coop(every now and then i take them outside for 30 minutes or so to free range while supervised) One of my chickens is getting pecked at and bullied. The chickens chase her around the coop pecking at her, not letting her eat food, drink, be with them, etc. I am very attached to all of my chickens and hate seeing this happen. Any recommendations on how to stop it? -and I keep my chickens in a coop because where I live there are lots of foxes, cayotes, hawks, etc. and don't want any of them to get eaten.
