Hi there and
to the forums!
Cloud and Cobalt are beautiful
Are you sure they're both males? To me, the budgie on the left appears to be female.
At any rate, if they really are fighting to the point where they are stepping on each other, definite action must be taken to ensure it doesn't escalate. How large is their cage? For two budgies, the minimum size should be 30 inches X 18 inches X 18 inches.
Also, you should have two of everything--favourite swings or perches as well as food and water bowls--to minimise the chance of them fighting. If you do all these things and still they are arguing more than light bickering and there is physical contact, they should be separated right away before more serious injuries are sustained
I'm glad that you've joined the forums as this is the best possible place to learn even more about these cute little birds!
Be sure to read through the forums, beginning with the Budgie Articles and the Stickies (threads "stuck" to the top of each subforum for easy reference) to keep updated on the very best budgie practices
If you have any questions afterwards, feel free to ask as we'd love to help!
Hope to see more Cloud and Cobalt soon, as well as to see you around the forums.
