I have two sultan chicks that just cry all day long! I am not new to raising chicks (have done it for years) but have never had chicks cry this much. Its almost like they are away from their family and are calling to find them. I have them in a brooder with 9 other chicks from Ideal, so they have been together from day 1 (or so). I've looked them over and can see no apparent injuries, or anything else that could be bothering them. They stop sometimes when they take naps, but will wake up and stand there calling. Any idea what could be wrong?? Thanks.
