Absolutely not that would be very dangerous.
The mama heating pad is AWESOME..
The chicks get warm from a mama heat pad ( MHP) by touching their backs to it. It won’t feel but a few degrees above ambient below the pad but that’s not how it’s supposed to work.
You throw out your thermometer and all these rules and all this worrying with an MHP. You raise it an inch or two a week to keep it the height of the chicks but you’ll be done in 4-5 weeks anyway as they feather out so quickly.
I am to the point now where I think anyone using a heat lamp just hasn’t learned about the MHP because there’s no way I would do anything different.
Chicks outside at Day 1, with an MHP in their coop. No messy dust in the house and you will be shocked almost to the point of disgust in 5 weeks when you compare photos of your chicks to photos of chicks someone has inside under a heat lamp (your chicks will look stronger, more feathers , etc)
