We have one chick who doesn't walk quite right yet. It mostly sits on its back end. It can get up and walk a little ways, then plops back down and sleeps. I'm just wondering if it is some kind of leg problem? We thought at first splayed leg, but it doesn't have a leg slipping out to the side, it just doesn't seem to get up on top of its legs much. It never just stands in one place like the others, it will run a few steps then plop. It has been hatched for about a day and a half.
