If you're able to check you Tama's hungry and happy hearts, though, it's probably not dead. Unless it "flew" after you checked and saw that they were all empty. If you have the date on your Tamagotchi set around Thanksgiving, your Tama might do an animation where it's being chased by a turkey. If it's still alive, this was probably it. Just make sure that you don't let your Tama's hearts drop all the way down again.
