I have 7 hens, all hatched June of 2011. I raised two EE chicks in my garage beginning in December, and after several sessions of having them hang out in the chicken run, separated from the big girls, I decided to take advantage of some warmer weather and integrate them into the flock.
At the one week mark, they are still very timid of the big girls, hanging out in the far corners of the run and running away whenever the big girls approach. At night, when I go to tuck everyone in for the night, I always find the two new pullets roosting outside of the coop on the top of the open pop-door. I've been picking them up and carrying them around to the people-sized door every evening and putting them inside the coop, up on the shelf above the nesting boxes, across from the roosts that the big girls use. They seem to settle down there every night and stay up on their shelf until I let everyone out in the morning.
Any idea on when I might see them actually going into the coop voluntarily? My big girls got the hang of it right away, but I kinda figure that the new girls are afraid to go in.
