1. Soak seeds in double the water for at least eight hours. Drain. Rinse. Drain.
2. Spread seeds about 1/4 inch thick in containers (at least two seeds deep).
3. Inside house temp is fine for sprouting
4. Rinse and drain twice daily with water.
5. After about six days you will have greens and a nice thick root mat: feed about now. You can vary this a couple days either way.
6. Lighting not necessary, I use ambient light
7. Don't sweat it, experiment
8. Repurpose or use inexpensive containers. Use several containers, some do one for each day of six and I use three and feed half a tray daily.
9. Rinse/wash containers with hot slightly soapy water after use to remove starches and prevent mold (which I have never had).
10. Do not feed only fodder. This is a supplement to regular crumbles/mash.
11. Provides fresh greens daily in winter which is wonderful, but i am now feeding it year-round.
12. Seeds, containers, water and attention twice daily. That is all you need.
13. Barley and wheat preferred, oats don't work so well. I use barley and it is wonderful. 50# bag is $14, and chickens get 1/2 cup equivalent of seeds daily six chix. That is cheap and super healthy food.
14. Couple pages back you can see my simple setup and pictures. And some other good simple setup pics too!

It is a big hit with my six chix, who are fed the equivalent of half a cup of seeds grown into fodder every evening. Full crops and they go to bed. Happy.
