To broody or not to brood

[Ilovemychicks08]

she is in the coop with the rest of the flock I have a Bator but she usually does it when its really cold out and the eggs die when she gets off them

I wouldnt let her brood in the cold

Yeah I don't think she should brood oh well I still have 1 proven broody
