That's what I'm going with next!If you will have chicks regularly, spend the money on something along the line of the Brinsea EcoGlow. Chicks love it and you do not have to worry about over heating or any other issue from using a heat lamp.
If you do not plan to have chicks regularly then use the heat lamp. I have used both. I prefer the EcoGlow type brooder. They are spendy, but I love it so much I have multiple (not all Brinsea).
