I'd love to have a heating plate, but a lamp has worked fine and I just observe their behavior in case it needs adjustments. No pics cause I don't have it set up now but I use tote boxes, small to larger when they're older. They're versatile, easy to transport, easy to clean..
I saw one farm with a neat set up in a storage shed lined with brooders. They used shallow stock tanks with heat plates and lamps. Of course they sell their chicks when they're a couple days old but I thought it was pretty cool.
And we use shavings.

Now que everyone who disagrees with me to quote and tell me how wrong X is



Maybe I should add disclaimers. Warning: use of a heating element can pose a fire hazard, use with caution and follow the instructions... Oh and someone will probably say pine shavings are bad they could have pests in them or it could hurt their lungs or electricity and shavings affect the environment or whatever... everything has it's pros and cons. But it works for us ok.
