It's the beginning of summer and I noticed my chicks were huddled as far away from the lamp as possible (I'm getting 30 degrees and above...in celsius, that is ). I tried turning off the lamp today for a short amount of time (mid-afternoon til evening). The chicks didn't seem to mind and were happy eating and drinking in the dim light of my garage. The chicks are 1.5 weeks old and 4.5. The brooder is big enough for the difference in heating requirements but I find they like to stay together in the "middle ground" I'm hoping this won't damage their growth or anything?
