For sure!
I spend so much time working with him he's grown into am amazing boy. He was so scared when he came to us hed flatten himself in his cage and stay there for hours even if we weren't in the same room, but with the love and care we gave him he's a sunshine. He is the bravest of our 6 birds, and just adorable. He calls to me when he wants something because he knows I will come, and he happily jumps to my hands just for love and treats.
I stopped playing games with online friends so I didn't randomly leave them to die if I had to run and take care of him, so yeah definately doesn't happen anymore ! It was just the one time thing, I told him sorry and gave him extra and that it wouldn't happen again.
We also ended up with two new rehomed budgies who were nervous (because their world got changed, their owners didn't want them anymore and they were neglected for a while before we got them </3) and Keigo, this same budgie who sat and waited for treats, is helping the new budgies open up to us. He flies around with them and comes to me for playtime and treats, and the other two are curious as to why and are slowly approaching us, even landing on my blanket next to me. He also encourages them to eat the chop i give everyone in the morning. He's such a good boy, and I am really happy to have him.
