Stopped at Keystone Mills in Cortland, trying their layer feed. It is a mash, so hubby insists they are wasting it (because he feeds them too much which leaves feed out overnight for the rats). The high protein layer 120 came out to $12.13 per 50# bag with the tax. I know everyone is always looking for alternative feed options.
I get 17% layer mash from our local mill, $10 and change, nice stuff. I ferment it, no mess no waste. I would suggest at least soaking it.
I probably will feed dry when it gets freezing though.
