Your hen is a Dom pied olpaine sky blue as she looks like my babies
Your male also looks like cobalt dom pied olpaine as you can see small white patch on his belly and his wings too (from that last pic you can just see his wings on the right.)
They both have pink feet so dom pied indicator
I think the male is slightly younger as his head bars are more pronounced.
Make sure they are not just eating seed, give them plenty of veg & fruit (50/50 seed and veg/fruit diet), and get mineral blocks too.
I would get rid of them plastic perches (dont like them personally as you don't get them in the wild lol) and get them natural wooden branch shaped ones as they are better for their feet and gives them something to chew on and its better for their beaks
Oh get them toys my birds love mirrors they will go mad for them lol
PS they look beautiful and look healthy to me
