My BO is a really broody hen, apparently they’re known for it. I found the easiest way to break her is to open up a new area for foraging if you can (i let them in the front yard for a few days lol) that way shes way too busy exploring and gobbling up bugs to bother sitting in her nest all day! Doesnt work every time if shes being really stubborn, then she gets a cold bath lol.
