No need for a heat lamp if you are using a brooder plate like that. You will just need a generic light bulb so they can see. It can be white - no need for red.
I would agree with this!~
I don't really know anyone trying to do both.
Plus, you are almost at the age where they might not need it soon.
I recently had a heat lamp explode. It was not fun and scary. So I'm inclined to think the danger of them to be real.
Some people also suggested to me a few months ago when asking the same question to try an electric blanket instead (water resistant type).
