I ordered 6 bantams from a feed store, 2 each Mille fleur Duccle, Old English and Silver Laced Seabright. When I picked them up they were limp, unresponsive and barely moving. I hand fed them water mixed into their food. One had splayed legs which I taped with a small bandaid. I lost 3 about a week old. When the 3 that survived got bigger (one of each breed) I noticed that none of them had any toe nails. What would cause this?
