(Apologies for long post)
I have kept budgies for a long time and had decided that I would stop as soon as my two elderly budgies finally died. But a couple of years ago I had them in the garden and an evidently lost young budgie flew to them and sat on their cage.
I took him in and asked around among neighbours. No one claimed him, so he became mine and I named him Daz.
The two elderly budgies died not so very long after - I think the new budgie was a bit of a shock to their established way of life.
Not wanting to keep a lone budgie, I bought a companion budgie for Daz. However, the companion was never as robust as Daz and died recently.
I don't want to buy another companion, as the logical conclusion to that is an infinite budgie loop - always having to buy a new companion each time there is a death.
So now I have an only budgie and I am worried about whether I can do enough to keep things humane for him. He has a huge cage (from the time when I had quite a few finches in addition to the budgies), and during the day I am decanting him into a smaller cage for short periods so that he can come into the room where I work, or the kitchen, or the garden, etc. I am also letting him out more frequently for free flights (not that he is really bothered about that). And I am spending a little bit more time close to him, talking to him, putting my hand slowly closer to him, etc. (I never tried to tame him when he had pals as I thought they were better off with each other.)
I also play budgie sounds from youtube for a little while most days.
Are these things enough? Is there more I should do? Should I try to find another home for him, with companions?
