No feathers on all toes is not a defect. Without seeing the pullet I can only say that yes, she could improve in time. If I could see her I could give you a better idea of what to watch for.
Ok so here is my girl she is a bantam Mille fleur Cochin, about 6 months old. She had coccidiosis pretty bad when we got her, so I'm thinking she will improve now that she's healthy.
