One of my chicks seems to have a wider stance than the others. I've seen pictures of spraddle leg, and it looks like the chick is doing the splits. This chick doesn't look like that at all, it just seems like her legs are set slightly wider apart then her nestmates. She can absolutely run around ok. If I do put her on a smooth surface, her left leg does seem to slide out a little bit. Is this ok, or should I be treating it?
