Has anyone had a broody sitting on a hidden nest outside the coop? One of my hens is hiding. She turns up only briefly twice a day to eat and drink and then vanishes again. She's very stealthy about it, I've got a general idea where she is - somewhere underneath our house - but I haven't managed to see where exactly she goes. She always waits until I'm not looking before sneaking away. I'm not sure if to leave her or try to catch her. How good are broody hens at avoiding predators? Anyone ever left a broody out there successfully?
