Now a week old, we noticed one of our new chicks has its anus in the wrong place. It's actually ABOVE the tail feathers instead of under them! Is this some sort of birth defect? Will this chick live, or should we put it down? So far all chicks seem to be eating/drinking/pooing fine. We saw this one has poo stuck to its butt ("pasty butt?"), and when we cleaned it off, saw the deformity.
