set-up

So i'm new to the bird world. When I was like 9 or 10 I had two Budgies but sadly I was a kid so I didn't do any research and they didn't have the best set-up. They had a straight seed diet because that is what the Petco employee told us to get. And yes they did both die maybe a month after...

Here is the set up of Miss Peggy's cage. The rope swing in the center she moves to where ever she wants to go.
