They're tough. You can pretty much only use it for soup, as it'll soften up and be pleasantly edible. You couldn't cook it up like normal chicken, unless you like chewin'.

If you had to, use a pressure cooker or Instapot to make a Chicken Parmesan, covered in marinara and a layer of cheese on top. Can also make soft and tender with Teriyaki sauce in the pressure cooker. It needs to be some kind of sauce. You can't do, say, a lemon pepper, as you need the pressurization to literally force the moisture from the sauce into the chicken.

Put an add up on craigslist and the next day you will have an asian family coming over to buy them. Use that money to buy more chics.
