Definitely like this thread. Not breeding ASFs, but plan to soon depending on what happens with my store ordering them.
With bedding, if you can't get to a feed store, PetCo sells a HUUUUUGE bag of pine, spruce, and fir shavings for like 6 bucks with a Petco Pals card. I used it for two 1.2 mouse bins a bit bigger than a 10 gal tank, cleaned once a week for about 6 months and still had over half of it left. There's also some cheap aspen shavings for a bit more.
Walmart started selling a 14% hog feed, but I haven't checked it out enough to know if it's a good buy. You can get a big bag of dog food (like 40lb) for 15 bucks that would work for rats if you got a low protein formula for seniors. Ol' Roy has the biggest bang for your buck at Walmart from what I've checked.
