Our flock of 14 has trimmed down to 10 and some of the girls are getting slow on egg production. We are going to introduce some new chicks to the flock via fertilized eggs and a broody hen. I have never isolated a broody hen before and I was wondering will the isolation be a problem for the new chicks and the rest of the flock? I guess my exact question would be does the broody hen and chicks need to be exposed to the flock while hatching or will cage isolation within the coop work? I don't want the new chicks to get pecked to death. I know that the broody hen will protect the new chicks and that is a possible problem. My hen and only hen that goes broody is a GLW with what I think has a Guinea gene and she is about halfway up the pecking order. I don't know how she is going to work out being a new mama but we shall see.
