Just checked the incubator I built. I can't believe how rock steady the temperature is holding. Seven days into incubation and I think tomorrow I'll try candling and see what's happening. The Speckled Sussex broody I've got on a 6 egg clutch of Welsummers is sure sticking tight. I think I've only observed her off the nest once in ten days. The other broodies I have wouldn't stick at all. I've managed to break all of them save one and tomorrow I'll spend a little more time working with her.
Hope everyone is staying reasonably cool during this hot spell. I've been trying to get everything done before 10am and then sit inside and watch movies.
