4 of our new chicks hatched yesterday and 1 of them looks fine but the rest don't! The first chicks is fine and going well but the other 3 are laying down, with their eyes closed and scrambling to try and stand up? The chicks feet go sideways while he is on his belly. I am using an infrared heat lamp in a cardboard box. They do have food and water. Only the good chick is eating and drinking. I have dipped their beaks in water but they dont seem to get it. Please help I am getting very worried about them.
