I use fermented feed for my flock, have been doing it since last October. Very easy and they are all looking good. I sprouted over the winter, fenugreek seeds and blk oil sunflowers seeds and oats but none of my flock were real keen on them, they ate them but it wasn't as big a hit as I thought they would be. Maybe they are just too spoiled on mealworms. And they are so darn expensive.
