chameleon eggs

[chameleongalore]

I have some 10 month old carpet eggs that are about to hatch but my 3 year old daughter ended up grabbing the container and dropping it. Im so upset as this is the first batch of carpets that seems to be doing well. The eggs all look the same but will they survive? i read that they will drown inside the eggs and thats why you shouldnt move them but wanted to confirm. Thanks for your help.

Hard to say...all you can do is try.

Yey im crosding my fingers, im hoping the babies are fully developed and strong enough to make it.

Happened to me once with panther eggs that were due in another month anD a half. My boys rough housed in the chameleon room and bumped the container on to the floor. Most of the eggs hatched a month early. And most of them did hatch.

If reptile eggs (chameleon eggs specifically) do not have a fixed air sack like bird eggs do, then turning the eggs should not be a problem (as my simplistic logic and many peoples experiences goes). But without actually knowing the anatomy of the inside of a chameleon egg in different stages of incubation, it is better to avoid turning the eggs. I myself did drop a few eggs from more then a meter high (accidentally, of course) to the wooden floor and did probably place them differently back to the bin. All two clutches (30+ eggs) of mine hatched perfectly except one smaller baby that drowned while hatching. I don't think turning once or twice is harmful. Dropping is of course harmful but they are not too fragile.

They do have a fixed air sac.

They do have a fixed air sac.

Never seen any article or any people gave me this fact when I was researching about this 2-3 years ago. Thanks, could you give a source?

"The chorion encloses the entire contents of the egg and together with the allantois helps the embryo breath by providing oxygen and disposing of carbon dioxide"...

Thanks kinyonga! I do not know what the "…"s between keywords meant, but the keywords helped me a lot. It wasn't any good to search "air sack reptile egg", at least when I did 2-3 years ago.
Apparently at the first hours/days of the incubation the embrios being positioned up, down or at the sides does not have a harmful effect. But eggs being turned in the middle (or maybe later) stages of the incubation does increase post-hatching lethality significantly. I did not have problems with hatching, but did have some "unexplainable" post-hatch lethalities (I think they were 2-3 months old babies that died this way). I also had some significantly bigger and smaller hatchlings but that probably does not have to do anything with the 2-4 eggs that dropped.
I in fact never cared about the positioning of the fresh-layed eggs while putting them into the incubation cups though. I wonder if turning them in those first 1-3 hours does inflict any harm in the long run.

Thank you again,

Edit: I found this with the keywords you provided:

@TCMontium are you saying that some of the embryos in the eggs you dropped where bigger than the ones you didn't drop?

The "..." s were just to separate the list of terms I used to search for the sites.

I wonder if dropping or turning eggs at certain times during the incubation causes a change in the nutrients available to the embryo because of damage caused to the internal connections between the egg and the embryos...a but similar to a twisted or squashed umbilical cord?

No, I do not remember which eggs dropped and which emrios/hatchlings were bigger or smaller. I am saying that dropping and turning probably does not have to do with the size of the embryo/hatchling, because it is very very improbable that the eggs I dropped were all the smaller ones when hatching. And dropping doesn't explain a bigger-than-all-other-siblings hatchling.

I hope you are not being sarcastic but since you are a herpetologist veterinarian I am inclined to do think that you indeed are being sarcastic. (or was it someone else, I am sorry if I mistake you with another user)

Hopefully the outcome will result in few casualties. I bumped my eggs pretty good once but never have dropped and they were ok.

@TCMontium... I am not a vet or herpetologist but i have kept, raised, bred, hatched a lot of reptiles in the last 30+ years...and I was asking a serious question so I could learn something from it.
I would be surprised if a bigger than normal baby hatched from an egg that dropped.

@TCMontium you might like to read the part I quoted from the Anthony Herrel site in this thread...
