Your MHP should be perfectly fine if they can all fit under. You'll need to adjust the height as they grow, but they'll probably only use it for a few weeks anyway.
A ceramic heat bulb is not a light, and nothing like a heat lamp. But I wouldn't add a heat lamp or any additional light beyond regular daylight. They need to learn to eat during the day and fill their crops before going to sleep at night. This cycle will help them acclimate and feather out quicker. My chicks were out in high 30s/low40s F and hardly every under the MHP during daytime at 2 weeks. Makes me wonder why "THEY" say chicks need to start with 95 degree heat and reduce 5 degrees each week.
Quiet chicks are happy chicks. How old are they? Mine stayed under and didn't come out hardly at all for the entire first day or two. I had to bring them out to make sure they got enough to eat and drink. It's good to push them under to make sure they know how to get warm, and also show them where food/water is at first. Soon they'll be running all over and you'll wonder why you were ever worried.So if the chicks are spending most of their time under the mhp does that mean its too cold for them in the rest of the brooder? The are very quite
