This is just weird. And the more I think about it the weirder it gets.
Several things come to mind. First off, I'd call an exterminator. If there are so many mice that you can see them, and you live in a condo not out in the boonies, then you have too many mice. If an exterminator isn't an option, get some mice bait. Every five & dime (Family Dollar, etc.), WalMart, and hardware store sells it. Comes in a little cardboard box (maybe 2" x 3"). You open the box & the mice think it's food, but it's poison. Place these strategically around you deck or patio. (But IF there are cats in your neighborhood, you probably shouldn't do this, as it's poison for all mammals.)
Where are you located, generally speaking? Is it a very urban area? Have you had frequent rains recently? Or are you in a draught?
My thought is that you have a population explosion going on, and as I said, they are eating your plants to get the water in the plants. If you've had potted veggies & such before, and this is the first year you've had problems, that sort of supports my line of reasoning here.
Next thought: can you get some bird netting and wrap your plants in it? Bird netting has holes that are too small for even a mouse to scoot through. (I wouldn't use chicken wire. Too big.)
