Hello, I am one week past Day 21 and decided that the last 10 out of 12 were not going to obviously hatch. I need to know what went wrong so I don't repeat this again. I kept temp at 99.5 (it sometimes spiked about 103) & humidity at 65%. I used Farm Innovators pro series (clearly not referring to the owner) circulated air incubator. So, air fan, egg turner, yadda yadda. I decided to open some and see what happened how far in the development they got. I've opened 3 so far. They are small with lots of yolk. Does anybody out there have any clue? Keep in mind these are from a line of Greenfire farm chickens that a friend of mine owns. Out of the two that hatched, one was smaller and had curled toes that needed to be corrected. Yes, I do have pics, but they are gross and I wasn't sure I should put that out there.
