From a few days ago, it was mentioned that you can get leftover grain mash from breweries. I called a local micro, and they said to bring 5 gallon buckets with our info and they'll call us when they are ready to be picked up! So cool to have a free food source!!! Thank you to those who suggested this. A bucket will feed my small flock for quite a while. It's cold outside so preserving the mash won't be an issue for us, and we have a freezer for summer months (though our flock will be growing)
