Great information, thank you! I live in the suburbs and only have access to pellets and crumbles, but a few years ago I came across a recipe for making my own grain feed. I haven't make it for quite a while, but will do so now and try the ferment. I'm a big fan of fermentation and sprouting anyway, why not do it for the girls? https://theherbanfarmer.com/urban-chickens-part-3/ (recipe on bottom of page)
