I got my first set of chicks which I set up in my garage do to cats. Do they need light available all the time or is it ok to turn out the lights when I go to bed? They have a ceramic heat bulb that keeps the floor temp around 80 Degrees. I also got five chicks which all seem to be doing great but I did notice one of them always runs around pecking the food out of the others mouths. Sometimes she will eat out of the dish but not often?
