I was going through the incubator and pitching infertile eggs, blood rings e.c.t. and i came across an egg that looked infertile from the top, but i couldn't find the air cell, so i turned it around and found out it was upside down for 7 days, and i saw this black unmoving dot that looked like an embryo and it was stuck to the side, there were defiantly no veins, should i keep it or just pitch it?
