収束ゾーンでのライフ: Life in the Convergence Zone

k, i know NOTHING about the care & feeding of avians, except not to bring bread to the tame(ish) ducks at the lake, and that buying the birdseed (May to Aug) at the nearby wildlife education centre raises money for the centre. But would it be outrageously mean to connect a 100ft (minimum) leash to a parrot's ankle *before* opening the cage? Because if Yosuke was MY bird and he took off on me like that, I'd want new handling procedures when he came home so it didn't happen again.
