I'm just wondering for those of you who have had chickens for several years--do broodys tend to go through it every year? Have any of you seen one go broody just once? Last year's gal, got puffy and hormonal for a week or so this spring, but didn't sit. Then she returned to normal. Last year she sat on non-fertile eggs, then adopted a chick I gave her--so I don't really know what to expect now.
