I bought a kitchen sprouter. The mason jars were working OK, but I had one go moldy so decided to upgrade.

I followed the directions, and put the sprouter by the LED grow lights. After about a week I had sprouts large enough to feed the chickens! I transferred some to a flat container and the chickens loved it.

The chickens have some competition for the sprouts, though. I forgot how good alfalfa sprouts taste!
