Yeah, I've done some sprouting on a smaller scale with success, but it is the larger scale....not really all that big, just want to get to actual grass that is green....this is causing some challenges. They will get slimy if not rinsed, and moldy, too. It takes a LOOOONG time for barley and/or oats to get to the grass stage. I've been using buckets with holes drilled and I set up a piece of hose in a scrub sink over a sump pump in my cellar. By the time I see little blades appearing, the gallon of grain is one big, tangled mass and only the top portion has anything resembling grass. In 3-4 days, there is just a little 1/4" sprout forming, which does dramatically increase nutrient availability. I've been happy with that, as it solves the increased protein needs problem quite easily. But I also want to get some vegetable matter into the producing critters and do so very cheaply, throughout our winters here.
So I am thinking of using the buckets until the sprouts are forming roots (5-6 days), then dumping them onto trays before they get too matted. Then the trays can be rotated near the windows to green up. But everything needs daily rinsing or white fur grows! I tried disposable cake pans, but they were too flimsy and got warped and didn't drain well.
I'll be giving up the project once I have something green in the pasture, and will be on the lookout for a solution in time for winter again. I do notice that the sprouts form grass blades much more quickly now that spring is in the air!
When do we get to see pictures of the lambs???
Its going to be so hard to make a choice! 
I could have sat down on a hay bale and stayed all evening, I kid you not! 
To you both!!!
