I have chicks that will be 5,6,and 7 weeks old Saturday and it's time to get them out of my house. They are some dusty little creatures aren't they. They will be going into the big girl coop which is 4x4x5 ft high. With temps starting to climb I was wondering if I needed a 250 watt heat bulb or would 125 do. Our Purina dealer only has 250 in red so I would have to get the 125 watt red bulb from somewhere else. Also they have been under a regular 100 watt white light, should I go ahead and get a red one or stick with white. Thanks
