So this is my first time breeding lizards on purpose, and I honestly don't even know what a fertile egg looks like.
I recently bought a trio of P. picta, and the people who had them before never removed the male, and never gave them any supplements. So naturally they told me that although the females have laid eggs before, they've never been fertile. So for the last month and a half or so I've had the male seperated and have been giving them lots of vitamins (calcium 2x a week, multivitamin 1x a week), and finally one of them laid a couple eggs.
Now the big question is whether or not they're actually fertile. I read that they look kind of pinkish when candled and that they'll have veins if they're fertile, and that they'll look really dark if they're starting to decompose and are no good. I've had these for about 2 weeks now (not sure how long they were in the tank before that

, though it couldn't have been more than a week from looking at the female) and at first the bottom quarter of the egg was filled with something light colored, now it's darker in color and it's more like the bottom third is filled with it. I also checked for veins and there are veins under the blob, but not above it where the egg looks empty. Also there's a little pink spot on the top of the eggs.
I don't know what to make of it. Them getting darker has made me think they're no good, but then I noticed the veins. Also they don't smell bad, though I don't know if they get stinky through that hard shell of theirs.
Thanks for the help!
