If you live in a colder climate when do you let a broody have eggs?

[what did I do]

I want to let my chickens do all my brooding this year but we live in a colder climate. When can I let my hens set? It is nice today but we are going to get more sub 0 temps this next week.

They will be kept in the barn when it's cold. We had chicks last of August last year that did just fine but we had some very cold days when they were young. The end of August is the latest we can hatch outside.

It is worrying when our hens decide to go broody in the middle of winter, but I've had broody hatches over winter that went very well. I kept them outside and the chicks toughened up quick and the moms did a great job keeping them warm. We didn't have any snow or to many sub-zero temperatures though. If you decide to let a broody hatch for you when it's really cold you can keep them indoors if possible and hang a heat lamp for them to help with the cold when the chicks start getting adventurous, but if that's not practical wait a bit for warmer months.
