Question

I had a wren once, it died the next day, and i have a chickadee, how is it able to live longer then the wren?

Answer 1

You don't know why the wren died, do you?  Maybe it was sick or injured.

Maybe the chickadee is not sick or injured.

Answer 2

It will live longer by letting it GO!  It is illegal to keep wild birds in your possession, they are protected by law.  If you keep it you risk getting fined or going to jail.  

Answer 3

were they both wild when you got them, how did you keep them.

wrens are bit nervous easily stressed maybe that's why but i don't know much about chickadees
