question about chipping hatchlings

[danceswithsavs]

I wasn't sure exactly where this topic belonged so i guessed i might have best luck in the breeder's section.
This is hypothetical, but something i *hope* may become a real problem for me some day:
Suppose i have a dozen eggs from my savs and need to reliably distinguish each individual animal from birth. Further suppose that they all must live together in the same enclosure.
I've opened eggs before and seen the yolk sac protruding. It gets sucked in and the scales of the abdominal suture intercalate and a scab forms. This is sort of the 'belly button' of a lizard.
Here is the salient part:
could a chip be inserted into the abdominal cavity just prior to the closing of the abdominal suture?
The chip would then be intraperitoneal, i think- but would that matter at all?
You can buy the chips yourself for a few dollars or so and wouldn't need a vet or cutting and no needles (those needles are HUGE) and no pain or trauma.
Has this been tried and does it sound like a reasonable idea?
Is there a way to tell the right moment when the yolk sac has just been taken in?
As an inferior alternative, is there a good way to mark them semi-permanently in a way that does no damage?

i dont know the effects of that, but keep in mind that a chip in the peritoneum might cause undesired effects - if the chip were to move, and instead be iun the abdominal cavity, it would be free-moing inside. that smacks of disaster to me. the only reason i bring it up is because before we found a donor for my father, he was looking at peritoneal dialysis, like his father did. im no expert, but the idea of a chip being able to freely move around the abdomincal cavity scares me. any trama to that region could possibly cause damage inside from the chip.

Very interesting concept. Im going to ask my vet about this. I imagine it would be safer to have a vet inject the microchips under the skin then they do not interfere with any internal mechanisms of the body, but what an idea!

oh please do! there are no vets within 100 miles of here for me to ask.
hatchlings are so small- i'm afraid of those needles that need to shove a 3/16 diam bead into them. If it could be done by using a hole nature already provided they could be spared such a trauma.

as am i! if it could be done, without later risk, that would be very very nice
