Last night I sat on floor with the lights off and began candling and numbering the eggs in my incubator!
The Cayuga eggs are too new for me to know, I am a novice candler after all. The Maran eggs are at day 7 now so are fairly obvious. I noticed two definates, one maybe and 3 that I think are infertile.
The Pheasants are more tricky. The eggs are small and thick shelled. They were definately fertile but it looks like they were found too late. They don't appear to be any further on than they were when I first looked. They do have obvious signs of development, but I think it was my tired eyes that told me they moved. I can also see what I think is the start of blood rings, which I believe usually appear when the embryo dies. So it doesn't look good for the pheasant eggs, but I'll leave them a bit longer and candle them again. Not too long though, I don't want anything exploding in the incubator!
