Fall brooding is at least as easy as spring brooding, and maybe easier. The weather is usually drier. The season is winding down, so there are fewer demands on your time. And there’s plenty of time for the chickens to become fully feathered and completely winter-hardy before the nasty weather sets in.
Pullet chicks brooded in October will be in full lay by April.
Mostly, fall brooding is just like spring brooding. If you’ve been brooding all summer long, you’ll need to drop your warm-weather habits and remember how you did things in early spring.
