I got chicks due to hatch out on monday and i'm worried about the temperature in the brooder, i'm scared i will cook them. Where should i position my thermometer to get accurate reading or should i have more than 1 in there in different positions?. I want to get the brooder up and running and get the temperature right before they hatch, just really scared that i won't be positioning the themometer right and i will end up killing them. Any help will be great, thanks. Marlene.
