does anyone have an updated spec list? this thread is so long it's hard to know what the current state of the art is for the MHP. In particular, is there consensus on the best height for the front and the back for one day old chicks. I'm at 3.5 inches in the front and about 2 inches in the back. I have bedding piled up around the edges with the towel draped down, in such a way so they can get in and out easily but still retaining heat. I have it pretty low, mostly so they have to hunch down a bit to get under it. they seem to be handling it well, the loud chirping has pretty much stopped. if I point a laser heat gun inside, on a chick I get around 99 f, which is about right. the ground is more like in the upper 70's. I am wondering if I should raise the front some so there is standing room? here is a photo about 20 minutes after the initial introduction. I placed them under to make sure they got that it was warm. I let them all take a good drink from a small bowel before leaving them with a nipple waterer and some food. the last time I checked they seemed to be picking up the nipple waterer technique quite well.
