If she is pooping in the nest then she is just choosing it as a comfy spot for the evenings....a broody will remain committed during the majority of the day also, though she may dash out for one or two short breaks.
She could be just considering... so a bit more checking is needed before giving her a clutch of her own. Try replacing the fake eggs with a couple of eggs you know won't develop to see if she is wanting the eggs to feel warmer for some reason. See if she treats them differently.
She's NOT pooping in the box. That's the main reason I'm wondering if she's considering it. I work during the week and can't really observe them much so I'll try to tomorrow and see what she seems to do during the day. I don't know if she's spending any time in the box during the day.
Even if she does commit, I might give her one or two real eggs along with the fakes, but I'm planning on an incubator hatch, so if she does commit, she'll get some of those chicks. It's too cold right now to risk her getting off of the nest and getting back in the wrong one. I'm using the wooden fakes, not sure if that makes a difference.
