Broody X 2.....I think I have an idea but need advice

[aart]

Ok, I get it now. My coop is 4 feet by 8 feet so I'd have to leave it outside. It's still awfully cold, it went below freezing last night here. My run is quite secure, and the pen I made inside the run has chicken wire on top as well (and is much shorter than the 7-foot walls of the run). I can't leave them out there all night though, right? That's why I let them back inside the coop at dark. I think they are secure from predators, but it's cold and I don't know that it will make a difference. It's the cool air under them, not the separation from the nest, right? All they've got in the pen is a bowl of water, a bowl of food, and a dirt floor.

It's both....and as RR said, disrupting them from settling somewhere comfy to sit.
You can put them on the roost well after dark, then get out there early and seclude them.
Might take longer to break them and a definitely a PITA, but it's what you've got to work with.
