About a month ago, I opened up the caged-in part of the coop to let my younger chickens officially move in with my older chickens (all are under 6 months old). Before that, I followed all the steps to properly incorporate the younger ones in with the older ones (range together, caged-off corner of the coop, feed and water all around, etc).. But its been a month, maybe more, and the babies are still a little frightened of the bigger chickens because the bigger ones are still pecking at them and chasing them away from food. One of my younger chickens is a rooster and he will fight back, another one finds a way to get in with the flock, but the last one is SOOO scared. She was once the cuddliest chicken I had and now shes frightened of me! I usually let the chickens range in our back yard all day but if I leave, I put them back in their coop since Im not there to keep an eye on them (we have a neighborhood cat or two and a couple of hawks that keep their eye on our chickens), and the babies HATE going in the coop and hide in the nesting box if its not bed time. Is this normal? Should it really be taking this long for them to get along? What can I do to make them all feel happier/safer? *No one has pulled out feathers or injured anyone.
