I don't do supplemental lighting or heating. I know that my way can slow things down a bit but right now thats okay when I get my egg business established I may do otherwise.
Thats good to know, as a newbie I am learning that maturity level in chickens is a big thing. Hoping these get started and then my 15 12 week olds will start late Spring just in time for my farmers market days. My younger ones are a mixed group of red sex links, easter eggers, dominques, barred rocks and BO's are any of these breeds in those tend to be substantially later than the others?
