I want to add more but need to know the best way. I am thinking when one of my girls goes broody I would get some fertile eggs to put under her. Is there an average age when a hen goes broody? Mine are 23 weeks tomorrow. Is there a season when it usually happens? I'm thinking this would happen next spring or so. Since I always see so many advertisements for chicks then. Or does it just happen when it happens? How many could a standard broody hen sit on? Is it best to keep them separate from our other girls? If so when they are introduced back into the flock what are the chances of the chicks getting pecked by the other girls? What age is the best age to introduce them back in? We have a smaller coop attached to the main coop. They would see each other but would be separated by hardware cloth. Would that help with the reintroduction? I was thinking I would get fertilized eggs from a hatchery. Is there pro's or con's to this? Is there a hatchery that you really like? I want to add more chickens but not sure about having a rooster. I currently have 4 Silkie roosters that I am trying to sell. We never got any girls so the boys have to go. I personally don't want to have Silkie mix chickens.
