Day 48, movement but egg is rotting?

Ah nuts.

There are a lot of times where the crucial defect doesn't show until the animal should start breathing on it's own. Given how far along that looks I'm guessing that is about when it passed.

It would have been a beautiful clown as well.

Nature has her way of deciding who will make it and who won't. Her balances for morbidity and mortality are a thin line i guess. Grats on those survivors!

Others are pretty much right. Only way you might be able to figure out an issue is a necropsy, which it may be too late for at this point and if the animals continue to have this issue in subsequent breedings, discontinuing them as a pairing.
