Success rate for first eggs

[Axle wiski]

I read somewhere that the first batch of axolotl eggs are mostly unfertilised. Is this correct?

Out of the ~900 eggs my leucistic recently laid (her first batch), more than 750 were viable. I'm not sure how "normal" this is, though.

My first batch had a 95% hatch rate.

My eggs started the "fold" stage 15 changes last night. Maybe 5 out of 640 eggs. Now after 8 hours 1/3 or 1/2 are there, and I'm sure more to follow.

No. A whole batch of infertile eggs is rare, even for a first-time female. First-time eggs may be smaller and harder to raise (less robust and healthy) compared to later batches.

In my first batch, there were two "twin" sets, but in one of them, the second egg broke, and the one left is smaller than most others:

Other's seem to be a good size:

Many thanks everyone! I asked because my golden albino Axol laid about 300 eggs on the 24th Nov but only a 1/3 have begun to develop into a distinct 'curl'. As it's 'our' first time I'm unsure if the remainder are viable. Should I expect to have seen changes by now? Also when posting in sample bottles, should I leave an air gap?

 

[usafaux2004]

I'm on Day 5, and about 1/3 to 1/2 of the 640 look like that stage 16 above. I'm sure more are at that point now. You're on day 8? I think they should be well onto looking like little "C"s by now.

 

[Axle wiski]

Yes, my thoughts too. These ones were laid directly on the substrate and are mingled with black sand. Oddly enough the others which developed well were attached to ornaments and elodea. Coincidence anyone?

 

[usafaux2004]

My girl laid hers on the fake grass, tree, bridge, castle. They knocked off most of them by 3rd day morning! Had to pick them off the sand, probably 75% or more.

They also ate about 20 between the two...

 

[Axle wiski]

I also wonder what Axol and Lotl consumed while alone at school. No late developers then with the sandy eggs? I'm at a loss. I had hoped to post but will halt for now.

Hope to find out soon
