Im hoping that some one can give me some insight and help teach me something about hatching eggs. As posted previously, I had my Blue Slate hen lay a total of 12 eggs, so I put them in an incubator. The first 6 went in 23 November, then the other six and 5 chicken eggs went in 7 days later. 4 of the chickens hatched the other day, the fifth egg never developed. Im still learning about candling, so was sure what I was seeing at first. Waited until the chicks hatched to crack it open, and it just had a runny yolk. I numbered all the turkey eggs as I got them, put them in an egg carton with the pointy end down, and keep them at a constant temp of about 70 degrees until they went in the incubator. It was a still air incubator I borrowed from a friend and pretty sure I kept the temp at 100 degrees, and the humidity at a good level. 10 of the turkey eggs had no shadows in them, but I waited until the chickens hatched, then cracked them open. Obviously too late to see if there was a blastoderm or what ever the term is inside, but 2 of them had a definite growth, or small white patch, but they were mostly just runny yolks. So my real question is about the turkey eggs. #6 and #12 were the ones that grew, so one should have hatched yesterday and the other should hatch next week. So I decided to crack the first egg open. The poult in it looked developed, had feathers and everything, but there was no movement at all. It looked dead to me. But there was no off smell. Ive heard about poults developing but then not hatching. Any idea what causes that or what I can do to improve my hatch rate? Is there any way to candle the remaining egg and determine if it is still alive? Should I be able to see movement? Can you mark on the egg, in pencil, and keep track of the size of the air pocket? Thanks for your help and advice. Really love this site.
