I have a barded rock who a month ago when we chickens out to free range was not with the group when we put them back in then two days latter my son found her and we put her coop. Due to weather and other events they have not been out to free range in the last month till yesterday. Now once again this bird was not with the flock when it was time to go back t he coop. Is this bid gone broody and gone to hatch eggs? I looked for her every where and cat find her.
