So I'm going to try to make this short. I had a broody hen who was sitting on Cream Legbar eggs, and Lemon cuckoo orpingtion eggs. I went outside (7:30 am) to feed the animals and she was gone out and about scratching around, etc . I'm not sure how long the eggs were without her but they were cold. I put the hen in with the eggs and she didn't want to have anything to do with them. So I brought them inside, and set them in the bator. I also had some more Cream legbar eggs, and lemon cuckko eggs inside the house so I wanted to hatch them all together. The eggs that were outside were set September 31, so that makes them 6 days old.
So my question is how do you do mix hatchings. I forgot what it is called but when the older eggs go on lock down, do I not open the bator and not turn the other eggs? Or do i turn them as fast as I can?
