Hi there and
to the forums!
Your budgies are beautiful. The blue one appears to be male, his mutation is sky blue normal. The green budgie is female, she is dark green cinnamon normal
Unless a budgie is Into (albino or lutino), they will have dark colored eyes. This is normal; since your budgies are young, they will not develop their grey irises until they are older. From what I can see, neither of them yet have iris rings, right?
Meanwhile, be sure to read through the forum's many Budgie Articles and "stickies" (threads "stuck" to the top of each subform for easy reference) to ensure you're up to date on all the best practices for budgie care!
Since you have a mixed-gender pair, be sure to take all necessary steps to discourage egg laying.
If you have any questions after reading through everything, be sure to ask as we'd love to help
I look forward to seeing more of your budgies! What are their names?
