My BO started molting about two months ago, and went broody about 2 weeks ago. Every morning when I let the hens out, I toss Ms. Broody out into the yard to eat something for-crying-out-loud. We're waiting out the broodiness, but I've tossed her out of the nest box a couple times a day since this started. Anyway, yesterday I noticed that she's completely bald on her underside. Her breastbone is bare (and kind of gross, honestly). Obviously this is kind of an issue since we live in Iowa and it's still below freezing here most of the time. Is this normal for broody hens to be bald? Should I worry?
