I don't know how big this room is but I'll presume it's big enough to hold me and my 30 new "friends" with enough room to move/defend/attack... Yeesh... Tough one.
Magpies. If they're in a room, they have less space to use their flight advantage. Badgers can have rabies, they have teeth and claws and probably weigh more... I'm really just basing this off of what I'm guessing... I certainly wouldn't want to hurt any of the little critters though.
Sushi or ramen?
