How can you tell the difference between a distressed noisy chick and a bored noisy chick! They are 3 weeks old and it seems the last few days they have gotten a little more vocal. I notice it more around dusk. They are in my dining room and once I shut off the lights they quiet down and go to sleep. They play eat and drink. There is no heat lamp in their as they are inside and they move about the kennel I have them in.
