im probly getting 8 chicks today or tommorow and want to know if I can use a 60wat light bulb.they will be in one of those plastic tubs and in my warm room.The bedding will be shavings so im just wondering if there gonna be warm enough.I usially use 250wat light bulbs but I accidently broke it so my mom would have to drive a very long way just to get another at the farm store.thx
