I just started raising chickens this past summer and know very little about them. Yesterday evening around 6pm, much to my surprise, I reached into a dark nest to feel for eggs and found a hen. The hen was still on the eggs this morning (3 eggs so far). Could this hen be broody? If so, what is the chance that she will be able to successfully hatch out the eggs in January? I live in VA where the average temp this winter is between 20deg(f) - 40deg(f). Thank You!
