Can you hatch year round? I live in the Northwest...are there times of year you can't/shouldn't hatch eggs? What would chickens do if left to their own devices (rooster in the flock, allowed to brood the eggs)? I don't have a rooster and I hatch eggs in my incubator, so I know technically I can hatch eggs any time. I'm hoping to do a round of eggs starting after a vacation in early to mid September. Is this a bad idea?
