Sorry I should've clarified - there was a bad egg plus the egg that "exploded" (the embryo was dead by the time the guy found it apparently) and the 3rd egg which seemed healthy apart from this odd lump. The guy was worried it was going to go the same way as the bust one, so he removed it from the clutch with the other 2 eggs for investigation. He was worried that these mites were inside the egg (in the lump), and were therefore going to burst out and infest the rest of the clutch.



The lump actually looked like it was growing out of the egg - kinda like the odd lumps and bumps that appear on eggs sometimes, but the reason my friend was concerned with this apparently healthy egg was the lump was appearing in the exact same place and shape as the one that apparently burst.



The remainder of the clutch has been cleaned and new substrate placed in with them. We've collected a number of mite samples to try and get them identified, so will keep you posted.
