We received 25 chick from Murray on Wednesday. I had the brooder all set up and had checked the heat lamp several times before the chicks arrived. Since we have had the chicks, we cannot keep the heat lamp at a consistent temperature. It is on a chain hanging from the ceiling, so we can move it up and down to adjust the temperature. We'll get it set make sure it's consistently 95 degrees for 15 minutes or so, think everything is ok, then come back a few hours later and it will be 80 degrees. Drop it down a link or two and it shoots up to 100. Any tips on how to keep the temperature more consistent?
