Yes, but that takes far more time than the average petty criminal is willing to dole out. Having to whip out wire cutters is a pain, they'd rather open an unlocked door and grab. Plus, the sound of wire cutters on a thicker gauge is loud. A simple lock is more of a deterrent than one would imagine.
And yes, locks can be picked. My former housemate schooled me on lock picking, since he is a lock pick extraordinaire, never saw a lock he couldn't handle. Not a problem if he ever forgot his keys. BUT again, time is the factor. Most criminals don't want to take the time to deal with a lock because anyone could walk in and see them in the act.
I suspect that, as is the case for locks on tie ropes and pen doors for larger animals, locks on poultry cages at fairs are a fire code violation.
