I had 4 copper maran eggs that were late to hatch days after the others. After day 25 I did an Eggtopsy and found they were all mal positioned, had unabsorbed yolks and a greenish hue to the abdominals. There was no odor, but I sliced one open and a bunch of green fluid poured out. Does anyone know what this is and how I can prevent it next time. I had three other eggs that hatched fine. 1 Silkie, 1 Favorelle, and 1 maran. Any info is greatly appreciated.
