I get quite a few of those out of my adult breeding pair. From the last batch of eggs that I raised I still have 2 one a darker grey than the other. I'll attach pics for you.
They are beautiful aren't they
mine never had such dark black dots as babies though but they did have the dots.
As for what they are there are 2 possibilities but I'm waiting for mine to get to breeding age before I can say which for sure. They are about 10 months old at present.
1st was Kaysies first though that they are hypomelanistic Melanoids
2nd and the way I'm leaning because of the red eyes is that they are a Melanoid that inherited the T+ gene that the coppers/Olives get making them a form of albino but not the usual true Melanoid albino if that makes any sense at all. I will of course have to wait till one of them lays eggs to know one way or the other.
I also got some Gold ones with grey/brown patches that are very cool but also have the red eye. I don't believe they are copper/olive but who knows. They have a lot of variation in the intensity of the patches too but the gold is always VERY yellow. Will add a couple of pics of a light and dark one of these too.
These are the norm for my primary breeding pair along with regular and low irridophor expression Wild types and regular old Melanoids
Parents are Golden albino (mother) and a mostly black and silver wild type (father) Both beautiful in their own rite but nothing out of the ordinary to look at really.
I don't get true albinos from them though so I guess Dad isn't a carrier of the albino gene.
Pics.
1st 3 are the same axie at different ages.
4th is the axie from the first 3 pics (left) with the lighter version (right) and one of the golds (Back)
5th is Lemmony the light version of the Gold
6th is Leopard the one in the back of Pic 4 and darkest of the golds from that clutch.
7th is one of the ones you have there as a baby that's just got it's back legs starting to grow.
