I feed a local feed stores Ground Pig Feed. Same as the Country Acres hog feed but its made 1st hand by the feed store owner. 100 lb bag is $10. I usually get a 5qt ice cream pale and fill that and they charge me by the lb. 10lb of feed is $1. So so cheap. Im gonna try there bird seed as well. Think its $10 for 25lb bag. They dont make there own bird seed though. The ASF's tear up some parakeet seed i know that much. So does my hamster. Lol. I think im gonna try making some sort of hopper for them so they dont make near the mess.
