I was at an auction a few days ago and overheard someone say free-range chickens are the best. You don't feed them a thing and they grow huge and ready for butcher. Then another guy said he bought a tiny pig and free ranged it to 500 lbs not feeding it at all. I was just thinking oh my gosh! Do they understand free-range at all???? You do have to supplement them with some feed. What is a chicken going to find to eat in the winter with a foot of snow on the ground to eat? It wasn't so funny as it was scary to overhear. They came from a big city 2 hours away to buy them some pets.
