Pip-pip-hurrah!

The thing most resembled the contents of the eggs that didn't hatch last year, so I wouldn't be surprised if it was unabsorbed egg. What's puzzling is how it was passed? The way I'm thinking, it didn't come out through the hernia and stump, because that would have opened up the abdomen. So the hatchling either regurged or pooped it out.
I'm not planning to try feeding until after the first shed, and for this baby I'll try the smallest red I've got.
No signs of pipping from Pearl or Annie's clutches yet. Beautiful plump eggs, no signs of rot, but no more pippies yet! I'm away on holiday a week Saturday, so I'm itching for these to emerge soon!

But are you sure it couldn't have been stored in the little stump you mentioned?

Kathy, you may have the idea. Maybe the substance was more fluid and was expelled through the umbelicus then solidified. That kind of makes sense.

The 'thing' was about the size of a peach fuzzy, so I hope not. (By which I mean if it came through the umbilicous, wouldn't it disrupt the healing?)

Oh, ad i was a discrete, solid lump, expelled on to moist towel.

Darn typos! AND & IT!

i've had one a few years back, it was like the end of a tail, well maybe bottom 20% of the body. It came out at a right angle, similar to that, but it was the actual whole body, full shin and everything if that makes sense.
it didnt survive.

So it was something like a siamese twin? or a re-absobed twin? scary...

That was really my only guess. I guess you would have had to take it to a vet to look at "up close" for a real answer. Sorry I can't be of more help.

Thanks for your help and suggestions Kathy, I suppose I should have examined the 'thing' more closely.
When you've had hatchling with a herniated stump of umbilicus, did it just drop off eventually?
