Do you mean throughout the year? I think there are folks that hatch all year long. I may do another hatch later, but wouldn't want itty bitty ones during really cold months. We get sub-zero temps occasionally where I am, so that would be hard. But if its warm enough year round, I would think any time would be ok.
You don't want to live in a cold winter state, incubate late fall and not have a coop with electricity so you can kick them out when it's time and house them inside ALL winter. It is not fun, I can tell you that. Love brooding inside for a few weeks, but OMG, never never again.I meant through the year. Sorry if I wasn't clear on that.
It really depends where you live and what your set up is.
