Further in incubation it takes longer for the veins to break down. If there is any sign of life, I can;t throw out an egg even at day 24, however, the chances of having a chick with no problems this late in the incubation is less and less. My day 24 ended up showing leg problems later on. Many people at this point would toss regardless.I think it's already day 24I put them in on the 1st. (They shipped out to me on the 27th) although, I did open the bator a few times... So temps weren't perfect.
So for future reference, veins don't mean anything? There could be veins, and the chick could be dead?
Opening the bator during incubation is not going to affect the eggs unless you are leaving it uncovered for extended periods of time. Some bators actually have a cool off period to mimic the time a hen leaves her nest. I would say that the temp was too low and the humidity too high over the average of the hatch.
