Hi Everyone: I am getting two new baby chicks on Friday and I thought I would try out the mama heating pad method this time. I made a half hoop out of hardware cloth and I am using a heating pad for a water bed we had. I then covered the pad with a towel and wood chips. The only problem I am having is when I touch the hardware cloth on the inside of the "cave" it is really hot to the touch and I am afraid of it burning the chicks. According to my thermometer the inside temp is around 90 degrees so I don't think the heating pad is set too high. Am I missing a step. Does the inside of the wire get lined with something.
