One of our hens went broody this past week so we are letting her sit on the eggs and hopefully hatch some out. We're in the mid-south where the weather depends on the day. We had ice and snow last week, and it will be in the 60's this weekend. What are the chances of this being successful? Will she be ok in the coop with the chicks or do we need to separate her and the chicks from the rest of the flock? They have a small run, but I let them out to free range (in a fenced yard) most days. Thanks!
