I just started getting into chickens a week ago or so when I built a coop and a small area for the baby chicks. Well, I just got my baby chicks today, 12 of them, mixed breeds. I purchased a 250 watt red light bulb to keep my chicks heated as I've heard the red is supposed to be better. Well, the red light is probably 12 inches above the chicks and they seem to be crowding around it, and I've heard that's a sign they could be too cold. Anyways, my question is how many lights should I need for 12 chicks, is one enough? Should I go get another? And my final question is about the behavior of one of the chicks. One of them sits away from the other 11, doesn't seem to move much unless I poke her in which case he runs a little ways and sits still again. Is there anything to be worried about with her? I'm really nervous, they're such fragile little critters, I would hate to see one die due to my ignorance of the subject. Thanks!
