Can you teach a chicken to chicken?

[LeahG]

We got 2 new hens yesterday at a swap meet. They were in good shape and weren't overage chickens so we thought they would know how to act like chickens...
Brought them home and let them out in the yard and it's pretty obvious they have not free ranged before and don't know what to do. The other two hens we have bullied them a bit, nothing that hurt them but it didn't look like they were used to a flock dynamic. Is there anything we can do to help them adjust?

Give them time to adjust. Birds hate change.

What sourland said

and not hover over them. The less you do things to them or for them and the less they know you are watching them, the better for the first few days at least.
