Ok another question, my chicks are doing good and everyone seems to be getting along. 3 are about 1.5 weeks and the other 5 are not quite a week. I pick up 2 rooster chicks Thursday and they will be only couple of days old. Can I put rooster chicks in with my others? Right now I believe have room for them. I have them in my living room, and I was wondering do I need to keep the 250 watt heat light on them or can I change it out to a 60 watt bulb? It is at one end of brooder so they can get away from it. I am so happy that they all seem to be doing well!
