We went to turn on the heat light for the night, and its burned out! I only used it for two weeks! So we suspended a heating pad just above the litter (they, 7 two and a half week old chicks, are in the coop already). They were scared of it, but when I picked them up from the corner and moved them to under the heating pad, they all stayed right where I put them. They have been so healthy and robust so far, I hope they are ok! It was 80 degrees in there, but I am sure it would go down about 5 or 10 degrees during the night.
