Only pic is that first one I posted. I am scared to open the incubator again... I have everything just right, and don't want to mess with it. Pictures through the incubator window don't look all that great.
Hopefully, since I painted the toenails of my first olive egg chicks, and all the rest that are pipped are Marans and one Leghorn, there should be no confusion of which are which breeds in the morning.
I am still very much hoping that lots more of the eggs hatch, as well as the rest of my olive eggs!
As to peeping, YES, they can peep before they pip.
Peeping means that they have gotten at least a tiny hole through the membrane, and are breathing in the air cell part of the egg. Sometimes they can sit there for well over a day, peeping, before they get the strength to pip, then unzip, then hatch.
Some hatch slow and some hatch very fast.
I always find it super frustrating. I always need to make sure that I spend very little time looking into the incubator.
I am a 'fixer' as well as impatient.... so I need to run away from the incubator so that I can sit on my hands.
