I had guineas years ago, free range (for tick control). When they'd go broody, I could never find them, and didn't know if they were still alive until they reappeared, either on an occasional break or after about a month of attempted incubation. In fact, I would only rarely find the nests when none were broody and by then there'd be a mountain of eggs from 6 girls, and I didn't know which would be okay to eat. When I did discover a nest, I was always surprised that it was right there so close, under a bush, or in the weeds...
