Thank you for your quick response. They are penned in a 12 by 12 pen and it is attached to a 12 by 12 coop that is always available to go in or out of. I believe it is one particular Rooster that is a big bully. My husband I have had a conversation as to how many roosters there should be with the hens. Your opinion ? LolWelcome to BYC. Either they are sick or the dominant roosters are terrorizing them. How much space do they have ? Are they penned or free ranged ?
