I *think* I know why my Princess would not take the chick.. She's been glued to that nest box for almost two weeks, just getting out to puff and screech at everyone and run back - just like a broody.. stays in the nest box at night, too..
But I caught her today - she's still laying eggs! Maybe she's 'pre-broody' trying to get her nest full? All my other broodies just go broody and that's that.
I don't call them broody until they stay on the nestbox at night for three nights and stop laying. Otherwise you're right, she's prebroody or just prefers the safety of the nestbox at night. Hope she stops laying soon and gets busy being broody for real!
