Purchased 4 Ameraucana chicks the other day. All seemed Ok (eating drinking) until day 2 when one of them was less active than the others. Was even weaker that night, barley able to walk, gave it a little warm sugar water. It is even worse today, can hardly stand up without falling over, separated her from the rest, afraid they would walk all over her. And placed a warming pad under her. Any one have suggestion? Or is she a goner? The other 3 are active and lively.
