I've also heat-pad raised chicks and it works extremely well. I use a viagrow heat mat of the sort you would use for seedlings, and (like the others) make a sort of cave out of it on wire with a towel wrapped around it. This works extremely well, the chicks feather out fast and seem to grow well. I may try a side-by-side sometime. But I find that the heat mats are bigger and likely to be more adjustable than the plates which I often hear are just too dang small.
