I set eggs on the 1st of the month, and they have not hatched yet. I opened one last night to see if they was even alive, And it was..It was absorbing the yolk. something I saw while opening the egg was the membrane seemed to be kinda tough I guess. I had the bator set at 98-99 degrees and 50 to 55 percent fareignheit. heard that having it higher would decrease hatch rate and might be better to go lower. Suggestions please.
