Good Evening, I have my first offical question. I have 12 - 8wk. old chicks. They have been housed in their new coop for the last week & a half and are thriving well. My question.....Do I still need the brooder light (infra red/250 watt) in the coop? The coop has good eventalation and two good sized windows. The past evenings have been in 60's but tonight it is suppose to remain in the 70's. Do I still need the light to prevent the chicks from seeing red if they should decide to bully one another.....I believe pecking order is already established. As far as heat, they definately don't need it.....lower wattage bulb perhaps. Replys welcome and appreciated!!
