On day 19 one of my eggs piped to the outside and began actively working a whole in the shell. How about 12 hours later two more eggs have started piping that would make it in the day 20 that in and of itself I suppose shouldn't bother me but what does is that two of the eggs the chick is backwards that is this a open the shell up away from the air sac or the narrow end. Now it has knocked a sizable hole in the Shell it is getting fresh air you can see it breathing but it is in the narrow end. How does that happen. I haven't rendered any assistance to getting it out of the egg yet I'm letting it work its way out of it if it can but I don't want to hurt its neck trying to. Why would eggs start to hatch a full two days before they were supposed to that doesn't make any sense cuz the incubator kept a steady 99.6 degrees with 86% humidity.
