I just got six peeps on Monday that were hatched the same day by a broody hen. One of the chicks' legs are not very strong. She can walk but with effort. She'll go a little ways and then stop and sorta sink back down on her behind and her legs will just sorta slide out to the side. She stays like this most of the time. She has eaten some starter but she's not really losing her puffy baby belly like the others yet. Anyone dealt with this? Will she get better?
