I had a chicken hen hatch out a peachick last summer. Since it was an only chick, I left it in with the chicken so it wouldn't be alone. I had them in a small chicken tractor and rotated around to fresh ground as needed. The little chicken tractor doesn't have a roost in it so they were on the ground at all times. The chick grew and as doing fine (he turned a year old yesterday). When fall came, I put him and his 'mom' in with his parents. This is where the question comes up... after putting them with the adult peas, the chicken would fly up and roost with the peas but baby never did. I have never seen him use a roost, he sleeps on the ground. Is this because he wasn't taught as a chick? Or is he just strange?
