I'm about to get my first chickens, (very excited!), and I've read a lot about layer feed and oysters and scratch and treats and... What I'd really like to do is raise my chickens in the least industrial way possible. That means I don't want to buy mega pound bags of feed if I don't have to. What did people do 100 years ago or 200 years ago before the shipping/idustrial world made it possible to manufacture feed for livestock? The chickens will live on a 15 acre vegetable farm and will obviously get their share of the veggie treats and insects people have written about. Also, how about watering in freezing weather--how did they do that before electricity? Thanks for your comments!
