Hi, This is our first experience using a heating plate in our brooder; we have previously used the old school heat lamp. My question is this - as you can't measure the ambient temp in the brooder, how do you know if the height is right on the heating plate? Should I try to put a thermometer under the plate? We have 4 chicks who are 9 days old. We received them when they were a day old. My chicks went under the plate the first couple days and seemed to like it, but I haven't seen them under it since. It's been around 95 with a heat index of 100 and our garage is fairly toasty. The chicks are quiet (no distress chirps), are eating and drinking well and are active and seemingly healthy. But I did come home to a dead chick two nights ago. There were no signs of injury, pasty butt, etc., and I know that can happen, but I guess I'm just being a worried mamma hen at this point. Any advice is appreciated.
