We just had a standard size chick hatch, but it was as small as a bantam chick and it had splayed legs. We tried the bandaids and tried medical tape and the poor thing just could NOT walk no matter how hard it tried and it was very distressed. We wound up putting it in a box on a towel backed up into a corner with a very shallow food and water dish right in front of it. Finally after 3-4 days, it started moving almost normally and not it is teetering around with the rest. It is still VERY small and it doesn't walk normally, but it is able to move around just fine.
In our case though, I think there is something wrong with it's joints at the hips. It just doesn't have a full range of motion and it's hips always have stuck out from the abdomen at a weird angle.
