mission impossible: operation broken egg

Hi!
Here's an account of an interesting event, documented by the series of photos I took last year.

In March 2006 my oldest Chondrodactylus a. angulifer orange female laid her first pair of eggs for the season.
She buried them in the sand under the clay hiding place she usually uses during the day.
During the process of laying one of the eggs evidently got stuck to the inner wall of the hiding place with a part of its shell.
(C. angulifer lay one of the biggest hard shelled eggs of all geckos, but also the most fragile eggs I've ever seen. Digging up their eggs from a pile of sand is like excavating live mines. They can blow up any second. :) )

I didn't know the egg was glued to the hiding place, so I lifted it and the egg broke right off, leaving a part of its outer shell on the clay pot.

It looked like the egg was buried there for at least a week or so, since it was obviously fertile, considering the blood vessels that were clearly visible through the still intact inner membrane.

Since the egg was fertile and still in one piece, I decided to take on an almost impossible mission of trying to save the egg and the developing baby inside.

With a little help from my trusted better half, her more steady hands, some Q-tips and melted bee's wax, we finally managed to repair the hole in the egg's shell.

We tried not to use the wax that was too hot, but I still wasn't sure the embryo wasn't damaged by the heat of the melted wax.
Like always I put both eggs in the incubator at 28 C.

...and then the long wait....
Two and a half months later the first baby from the undamaged egg hatched.
Three days later, to my very pleasant surprise the second baby hatched from the damaged egg. It looked great and seemed completely healthy.

Two siblings. They were both eating great and growing rapidly. They turned out to be a pair (male and female).

Together with some others they went to the US with Nathan last September.

I hope you enjoy this little educational story. :)

Hello Mat.

I have 2 other cases report of successfull "broken egg" incubation.

2 years ago my female Chamaeleo deremensis has laid a big clutch of 25 fertil eggs. During the excavation and manipulation 3 of the 25 were damaged after separating (Cams eggs are often sticked together) I can see a little fissure but lack of discharge and unbroken inner membrane.
As surgeon I use some biological glues and I was lucky to have some commercial samples out of date for surgical use (the price of those glues is crazy !!!).

I used Tissucol an heterogen multiprotein biological glue with success for 2 of 3 eggs.

July 2006 same complication with a Nephrurus levis levis egg I have damaged during wall enclosure separation (It was laid against the wall and remained almost 10 days) without any fluid discharge and inner membrane damage.
Same technique with Tissucol and success after 2 monthes incubation.

It was in all cases little soft shell damage without fluid discharge and intact inner membrane and not so impressive as your egg damage.
I think the major condition is to recognize the damage as quickly as possible before bacterial / fungal contamination.

But your success is really great with a hard shell egg !!!!

Hi Nicolas!
Wow, that's very interesting. Those glues must really be something special.

I usually manage to break one or two angulifer eggs per year by accident, when digging them out. Or the females break them themselves. They are soooo fragile.
That was the first (and only) broken angulifer egg that I managed to save.
They are usually damaged beyond repair.

I didn't know what to use at first to cover the hole and then I just tried it with bee's wax, which was handy from a candle we had at home.
It was a desperate situation and I didn't have anything to lose. :)

Anybody else managed to successfully repair and incubate any other broken eggs?

I hope to have some eggs next year from the 4 red jewells I got from you last year !!!!!!!!!!

They are in a perfect condition and eat like crazy little pigs.

I'm very happy with all your geckos (splendens are also great) and wanna tell you you're making a great and serious job.

Nic.

Thank you very much for the kind words, Nicolas.
Check the Paroedura forum, to see something really nice. :)

Matjaz,
how deep is the substrate where you usually find your eggs?

I just have one laying female this year, and she broke the first 3 clutches :(

Bee wax :idea: good idea!

Hi David!
Sorry to hear your female broke the eggs. I hope you have better luck with your future clutches.

I have about 4 to 5 cm of sand as a substrate, but specially females dig around so much that the substrate is 1 to 7 cm deep, depending on the site.
I try to observe my females every night to see, if they have already laid the eggs. They usually start digging in the evening and when I notice a new pile of sand and the female suddenly changed from ultra wide to thin, I go looking for eggs. I always try to remove them the same night they are laid.
Sometimes the eggs are laid directly on the bottom and sometimes there's still some substrate underneath.
They are usually laid in the dry part of the substrate, which makes them far easier to remove.

If they are left in the terrarium for longer, they could easily get destroyed.
You only have to look at them the wrong way and they will break. :)
And to prevent the eggs to be glued to the bottom of terrarium, I put an ordinary plastic bag on the bottom (at least two layers of plastic), under the sand. If the eggs get glued on, I just cut away a piece of plastic with the eggs and transfer them to the incubator together with the plastic attached.

Regards, Matjaz

Hi Matjaz & Nicolas ~

Your well-documented accounts of saving damaged eggs are amazing! I found this a very interesting read!!

That was very interesting to read. I actually had a small piece of a tokay egg crack like that once. I didnt do anything to it at all and a baby hatched out of it just fine. I had pictures of it at one time but I dont know where they are now.

I actually had another angulifer egg, that just suddenly developed a long crack in the outer shell towards the end of incubation. (I don't remember exactly, but it happened about a couple of weeks before hatching.)
The baby hatched just fine, actually using that crack to crack open the shell.
A big baby, I guess. :)

This is the baby I'm talking about.
I already posted these photos some time ago, but since they are so nice, here they are once again. :)

Actually I have the same problem like matjaz.
When I found the last clutch of eggs from my C.angulifer I didn´t realize that one egg was stuck to the ground.
This egg looks very similar to the one from matjaz.
I sealed the hole with Vaseline and hopefully this will work for me.

Great thread and good work matjaz!

best

I know this an old post, but I just read it again, and all this is info that be referred to again and again, so....


I had a bunch of White-lipped snake eggs that were about 30 days from hatchin, all glued together in a bunch from laying. Well, one of the eggs had been bad, and had shriveled up, so I thought I would pull it off the bunch. In doing so, I ripped one of the good eggs. Not wanting to lose a baby, I grabbed an old eggshell from a prior clutch, cut a "patch", wet it, and applied it to the hole in the good egg.

Voila!, homeostasis was regained, the patch held, and now Ive got a bunch of Crotaphoepeltis hotamboeia that I need to get rid of! Anyone?

Pm if interested, Not Kidding!!

So its not a gecko, still good stuff, applies to all parchment shelled eggs, such as leopards.
