I read that this is just as deadly for other beings - unintended victims like nonpredatory wildlife etc, - so...................... careful everyone.
OP, the hardware cloth floor is tough stuff - they will not be able to get in and your birds will no longer be sitting ducks. I would also let the hardware cloth run up the walls 6 inches or so if you can, so they can't get in around the edges. Then maybe put something on the floor so the birds don't get their toes caught in the wire when walking on the floor. A project, I know, but it only has to be done once..thankfully!
