My Budgie is not pooing as much tired, and ate a lot of food early last night .

He is 5year and 4months old. Is he getting old?

A little perkier this morning but sleeping a lot now. 

He eats his grit and seed. Can you please advice me what to do, he is such a darling.

Has changed  start of this year , like not playing with his bells.

I suggest taking him to the vet if you can  they will know what to do, hope he feels better soon!
