I have a single silkie hen that is about 2 years old. I have had her since last August. She lives in an Eglu in the back yard; free ranging in the yard when I am home on weekends. She has had 2 periods of broodiness;other than that laid eggs 4-5 days per week. I know chickens are socail and have considered getting her a friend. At this point would that be a good idea? Would they share the coop or would they fight? Could I get another bantam breed that might be a better egg layer than a silkie or would it be best to stick with the same breed?
