This morning my most active chick pipped sometime between 1am and 430am. It's doing great! Strong chirping sounds, nice white, flappy membrane around the pip hole, moving around. I suspect it will work its way out by this evening! The other two have no signs of breaking through yet, but there is also no smell, so i have no reason to believe anything is amiss.
I just wanted to clear up a few things
1. The eggs were gathered over 2 days, but set at the same time. Is it reasonable to expect the other 2 eggs to pip within 24 hours of the first egg? Or do people expect the eggs to HATCH within 24 hours of each other when they were set together? Expect isn't a hard and fast term for me, more of a guideline to help me keep an eye on things.
2. If they dont pip, and there's no movement (i havent seen any movement in at least 18 hours but i think that's good from what i reading-get into position, rest, pip, rest, zip) waiting until day 22 or 23 to make a pip hole is the game plan, right?
3. Are there any signs that a membrane is going bad once the pip hole has been made? Does it discolor or stop being so flappy? Right now it moves like tissue paper (real life, i disinfected a pipe cleaner and put it through the vent hole just to see what the membrane moved like because i am an overly curious person).
Generally what's going to hatch usually hatches by 48 hours after the first hatch, with exceptions of course. Eggs that are in a hot or cool spot in the bator (and even forced air bators have them) will hatch earlier/later (respectively).
Smell means nothing. Seldom will a quitter smell and let you know it's actually quit, especially late term quitters.
Each egg and chick is different so you can't judge one by another.
As for making a pip hole, if there are no internal pips, putting a hole in the egg is NOT going to help a single thing. Now if you have an internally pipped egg that has been internally pipped for 24 hours, then making an artificial pip is understandable, (though it won't hurry things up any.)
If the membrane becomes brown/yellowish and starts looking leathery that's a sign that the membranes are drying and I would pull it and moisten the membrane and check to make sure that the inner membrane isn't drying and glueing to the chick.
If the first one hatches and you still have no other external pips and you are curious enough, you can, (yes, you can open the incubator) candle and see if there is any sign of internal pipping or movement.
