Fermenting animal feed in the winter

I have been soaking and slightly fermenting feed for my birds and pigs, but winter temps slow the fermentation. My temporary solution was to submerge the buckets in an overflow from one of our hot spring sources.. in this case the domestic supply spring. Future plans are to build a greenhouse with a radiant heat floor powered by this hot spring water. Essentially a giant heating pad for winter growing, seed starting, and feed fermentation station. This will back up to a trailer, and I want the adjoining room to be a chicken hatchery/mushroom fruiting area. Just wanted to share.. any input welcome, and wishing a great day to Permies and all..

Wow! Great idea, using what you have to make more out of a perhaps "less-than-optimal" situation. Good thinking! Constraints do indeed force outside-the-box thinking, and you proved that again!
