Thanks for the info....however, I'm not hatching them for a breeding program or to better my program...simply hatching them because I want one as well as a few of my chicken friends as egg layers only. I don't own a rooster so I had to but eggs and she would only sell them by the dozen. These chicks are now due to hatch in 8 days so there is no way I can just throw them out. I took these pictures on day 5 or so. I candled them again last night but didn't take pics. They seem to be growing as expected as of now. If they die, them so be it, but I can't just let them go now. It's just who I am. Here is another pic...I thought I had sent three but only one came through. [/QUOTE]
I agree with all that.
When they're not your birds you just don't know.
If I have a pullet egg that is XLG or jumbo, I suspect a double yolk and don't incubate.
