I have 5 Austalorps and one of them is broody and will not get out of the nesting box! Even if I collect the eggs, she still sits there, no food, no water. I've been making her get outside (physically move her out of the coop!) so she eats and drinks, once a day or so. How long does this last for? My little daughter usually likes to collect the eggs but with her laying there, it makes it hard! Thanks!
