One of my Millie Fleur Chicks has a bad leg. He will only use one leg, and hops arround like the other one hurts. When he is lying down, he lays on his hock and his foot sticks up. It is like too far foward. I tried the spraddle leg thing, but he just holds his leg in the air. What is the cause of this? he is perfectly fine other than the bad leg. If i cant fix it, he is gonna get the brick treatment.Although i wont be the one giving that treatment! Help Me!
