i have gotten some monster eggs fromm jj and quail lady and in my experience not only do they hatch but they hatch first and strongest, like i said thats only my experiences.
Absolutely they will hatch. There is probably a jumbo bird somewhere in the woodpile. In fact, I take the larger eggs and hold them for their own hatch, because i know I have a few jumbos running around the pen. All the quail in the photo below hatched within hours of one another. The Italians came from larger eggs.
You can open a cour to see if they are double or triple yolks. My jumbo brown and Texas A and M eggs don't fit every hole in the turners so I put them on the outside holes and the others in the spare chicken holes.
