We just received one Rhode Island Red and two Ohio Buckeyes. They are one day old. One OB and the RIR are running, eating and drinking. The other OB is sleepy, has no interest in eating or drinking and only wants to peck the other two. She has enough energy to bother the other two! Should I worry? Again, they are only 24 hours old, no pasty butt and her eyes are bright. Thanks so much.
