Trying to get my MHP set up for my chicks arriving on Monday. I just got the heating pad (same one as discussed in this thread). Had a hard time finding one w/o auto shut off. It has the 6 heat settings, so I thought cool. Problem is that after 4 hours it isn't very warm under there. Only about 85 degrees and the pad is still on. I just don't think that will be warm enough for just 2 babies. Comments? Suggestions?
