I bought a new budgie 4 days ago. It didn't eat anything the 1st 3 days, yesterday it started eating. It stands still in a place all day and rarely moves. 1-2 times a day it flies from one side of the cage to the other for some times, but all other day sits somewhere and looks. It does not play, move, sing, explore the cage.
I want to ask, is it normal because it is still adapting in his new environment, or is it not normal?
It is a male and it's size is something smaller than the others.
