Just picked up 2 Golden Comet chicks (4 weeks old, stills have some fuzz, mostly feathered, will give them heat at night). When the older hens saw them they got real vocal. Is that normal? They have quieted down some now, 2 walking around, one laying by the fenced off area where the chicks are. Here is Henny & Penny in their fenced area. They are scratching around, and chirping.
