We have staff members who are excellent at determining genders and I've contacted them so they will see your thread when they are next on-line.
They will be able to tell you for certain what gender King is. Many veterinarians (unless they are Avian Veterinarians) are unable to determine a budgie's gender.
Body size doesn't make a difference with regard to your budgies' gender.
Some budgies will talk and others will not. It depends on the bird.
I had one that was talking quite a lot until he was introduced to his current flockmates. Now he has reverted to only "budgie talk". LOL
Oh ok thank you so much.... Please do...
