I had 2 budgies that a bought about 6 months ago, one male and the other female, they bonded well loved each others and even started mating but the female died due to egg binding about a week ago, he seemed well this whole week and was even happy and singing usually, i even made him trust me and started feeding him from my hand and spending time with him, now i left him alone like 2 hours ago to have some alone time and when I came back I saw alot of feathers on the bottom of the cage that weren't there when I left, I'm panicking because I heard that they do that when they're depressed until they die, and that they get depressed when their birdmate dies, but i thought he was fine and wasn't depressed, please anyone help is this normal? should i return him to stay with the shop birds or get him another bird friend??
