I've searched and searched and cannot find anything on this...I gifted some hatching eggs recently. The hatch was unsuccessful, and the hatcher broke the eggs to see what was inside. She indicated several were about 3/4 developed, but "the surrounding yolk and liquid had curdled and turned all sorts of greens and blues and grays." This must be some sort of bacterial issue, but I've never experienced it before in hatching any of my eggs. Does anyone have any clues? Thanks for your feedback.
