Have thrown them out. No sign of life when candled and bobbed in water. Brian who owns the incubator came round today and tested and reset the temperature gauge Going to disinfect it and retry with four more I have here. (dated 4th/5th/6th and 7th)
He also said not to put water in till 2/3 days before hatching. So if setting date is tomorrow, hatching date should be 29th or thereabouts. I'm away from 24th to 27th and don't want my dog sitter to have any hassle - how early might they be? If they hatch on the Monday I'll be back, but wouldn't want them hatching over the weekend unless she can leave them in the incubator till I get back. I could leave them a few more days before setting, as I'm still getting an egg every day from Jack and Jill, so could use the oldest ones and set the newer ones.
