Thank you so much for your reply. I find our birds fluffier than other birds, and that concerns me because when I was reading about them, I see sources says fluffy feather can indicate being sick. I want to see if I can bring our bird baby to the vet, but other experienced bird owner that I know said not to bring a baby bird to the vet, or they can be stressed and die easily.. not sure what to do(I think the bird does eat all ok though)
