So true, that is why I do dry hatch. These girls had been laying for close to a month and their eggs never got bigger, but I also don't think dark cornish lay big eggs, they were bred with a BR and he is huge. I should have followed my instinct and not added anymore water. But our air is on and it tends to dry stuff up, even though they are in the closet. The Wheaten OE's were also pullet eggs and everyone I set hatched.
