That 21 day thing is a target, not an absolute law of nature. It's not that unusual for eggs to hatch 2 full days early or late. There can be different reasons for that. So try to relax. You are doing OK.Guys my chicks are coming already but they were supposed to hatch in 2 more days.
Heredity, humidity, how and how long they are stored, and a few other things can affect when they actually hatch. One big thing is average incubating temperature, if the average temperature is a bit warm they can be early, if it is cool they can be late.
With my own eggs, whether under a broody hen or in an incubator, my eggs typically hatch a day or two early. I think heredity has a lot to do with that since I've calibrated my incubator and it happens with broody hens. That's why your eggs being two days early doesn't bother me. The first time it happened it did excite me, but not any more.
Sometimes my hatches are over in less than 24 hours after the first one hatches. I've had some drag out more than two days, well over 48 hours. In one of my more worrying hatches I had one chick hatch late one day, two days early. Nothing, no pips or anything, until about 24 hours later I saw a couple of pips just before I went to bed. When I woke the next morning I had 16 more chicks in the incubator. Each hatch is different.
Yes, chop up some fruit and put that on some vanilla ice cream. Enjoy it as you calm down. As far as the eggs go, leave them alone. There is nothing you can do to help, there are things you can to do hurt them.I've got my air cells marked and both are popping bits of shell from the bottom of their eggs. Do I do anything?!? I thought they were supposed to come out where the air cell is. Is this okay?
No, see above.Do I need to orient the eggs differently??
Let us know how it is going tomorrow morning. You'll probably feel better about this then.
