I know that hens have yolks of varying sizes and at different stages of development growing in them pretty much all the time. But when a hen catches the broody bug, what happens to the undeveloped yolks inside of her? Perhaps does her body absorb them to use to help bridge the nutritional gap since she only gets up to eat once a day or so? Maybe that's why broody poop smells so different? Or maybe they just go into suspended animation only to reawaken five-ish weeks after her chicks hatch and pick right up where they left off? Or does her body know it's going to be going broody and stop developing yolks a few days before she starts sitting? Can't find the answer when I Google it so I figured I'd ask the chicken experts on BYC! What got me thinking about it is that my broody mama who got sick and had to be taken off the nest at 15 days (see my thread Broody Mama Worrying Me) laid a shell-less egg, though it had a normal size yolk, right off the roost her first day back in the coop and then didn't lay anything for two weeks. She finally laid an egg again on Saturday, nearly white (they are light brown egg layers, orpingtons) and sort of small but now she's laying normal eggs again.
