New to backyard chickens!!! We put up a coop & built a run during Christmas, looking forward to watching the “teenagers” turn into beautiful egg-laying mamas!!! Love watching their mannerisms & behaviors. Introduced 2 smaller birds to the gang 2 days ago, the bigger girls are bullies! No bloodshed, Put out extra food and water for the youngers, but they wont let them come near the coop during the day. How long does this usually last? Thanks!!!
