I have 18 chick that are about a week to 2 weeks old. Five different breeds but are all brown egg layers. One of them peeps all the time. I have tried different feeds and waterers. There is enough space and the heating is right. None of the other chicks are having any problems and "Peep" seems healthy but just peeps all the time. Its not loud but its like little chirps in sets of 3 or 4 peeps if that makes sense. Like I said its the only one out of 18 that does it. Does anyone have any idea on why its doing this? It will stop for a little bit if I hold it for a while.
