Sunshine is a beauty, for sure! I was just at our Petsmart on Monday, and I fell in love with every budgie there!
Walked away with 100 pound weights on my legs, if you get my drift. MAN those little budgies are cute.
Made the mistake afterward of going to Petco (what the heck was I thinking?) NEARLY lost my stoic reserve there, but the budgie I would have taken home had a leg band on, which was a deal breaker for me. I asked at the store if they could remove it before it left the store, and the guy called another employee who said 'it would be against the law for them to do that'. Hmmmm.... I doubt that is true, but I can't prove otherwise. I just think they didn't feel comfortable doing that.
Everyone has GREAT socialization tips above, so you are doing great.
Budgies hull their seed, so many times the dishes will look full, but it's empty hulls, so add food daily, just in case you didn't know.
