It's been awhile since I've been activie on TB, so I thought I'd might as well share some pictures.
Two of the budgies in these photos aren't mine (the ones with the yellow faces). Their names are Daxter and Tess, which appear to be both female, but the owner of Daxter seems to think that he is a boy still (the one with the REALLY brown cere). So if anyone wants to offer their opinions on that, feel free.
When my boyfriend and I visit his family, we bring our budgies with us, and they hang out with my boyfriend's brother's budgies. Sometimes they get along...most of the time it doesn't seem to be that way, lol. Buster and Daxter seem to like to get into trouble with each other, while Meeko and Tess seem to want nothing to do with it.
I guess it's a territory issue, but there's no physical fighting or anything, just bickering mostly.
And no, they don't all share that same cage when visiting, they were just out for exploring.
