I had a hen that hatched several chicks last year. She has been sitting on some eggs lately for some time and I was going to let her hatch them on her own . Last night a dog got in our coop and killed our chickens. I put all of the eggs in an incubator and want to attempt to hatch them. I know you have to turn the eggs except for 3 days prior to hatching. The problem is i don't know how long she had been sitting on the eggs. I know it was between a week or two. Since I don't know the exact time I have no way to know when to stop turning the eggs. What should I do? Should I just continue to turn the eggs until they hatch? Can candling help give me an idea when to stop turning?? Any help would be appreciated.
