My 3 ladies are about 11 weeks old and have been in the coop for a month now. I let them into the run a week and a half later. The 1st couple of nights I had to put them into the coop and lift them to the roost at sundown. The 3rd night I had a surprise. I saw no chickens in the run! I peeked into the coop and there were 2 birds on the roost. They had never ventured up on their own. I was so proud of them, but where was the fat Faverolle, Miss Raye? She was hunkered down under the coop ladder all comfy and alone. This has become the norm every night. She stays out all alone and she actually seems a bit fearful of the ladder. I've tried ladder lessons with raisins as bribery. No dice. Will she grow out of this or is she just not getting it?
