Great story, well told. Like everyone said, it's absorbing, conversational, and funny. A few minor points: Right at the start, you tell us that the Amy Sue can fly - "Look at her, just staring up at the ceiling, wanting to go right through it and play with the clouds above. She's just straining against her tether, wings beatin' furiously." It would be more fun to find out for ourselves, as the story progresses. Then you'd create a sense of curiosity, and a little dread, with the horns growing. Is Amy Sue really turning into a demon pig? Well, as it stands, we know she's not, so the opportunity for suspense is missed. You'll need a title that doesn't give it away too. The bits in brackets don't need to be. They're funny enough to stand on their own. If you want them to be separate, maybe italicise them to make them appear as the narrator's thoughts. The build-up to capturing Amy Sue is great, really comical. The actual capture could do with a lot of expanding ("but we managed to catch Amy Sue anyway" - a bit anti-climactic). There's a lot of scope for some winged pig/farmer slapstick here and you could definitely handle writing it - you're clearly very good at that. Like I said, it's a great story. You could certainly find a publisher for this. =)
