I’m pretty sure I got the Brinsea Safety 1200 model, kept it adjusted low enough so it touched the backs of the chicks when they go under it so it keeps them warm. They will come out when they get warm enough.Which model Brinsea heater did you get? I purchased the model 600. Says it's good for 15 chicks, but looks too small for that many. I'm getting 6 chicks.
I read too many horror stories about fires from dust and feathers flying and touching light bulbs/ heat sources , the Brinsea does not pose that risk.
