Ask the feed store if it has been treated--pesticides, fungicides, fertilizers. If they don't know, then have them find out (they know where they sourced it from). No you do not want to feed wheat containing any of those to your chickens, it doesn't matter how much you soak it.
Yes, it will attract fruit flies/fungus gnats/etc.. I finally had to move my ferment buckets outside because of them. A helpful toad/spider team took up residence nearby so I don't have many insects around the buckets at all.
A few. Soak them for 24 hours first. I think they were ready in 3ish days, but it's been a while as the garden was providing the chicken snacks this summer. I'll do sprouts (chickens) and fodder (goats) after the greenery is killed by frost.
Just the mung sprouts and chickpeas so far. Honestly, even cooked the other types require significant seasoning for me as I find them too bland to eat as is...wasn't tempted by the sprouts.
Actually the toxin in raw beans is destroyed by either cooking OR sprouting, so any type of bean can be used. I've done all sorts including mung bean, chickpeas, northern beans, pinto beans, black beans, the aforementioned lentils, etc.
Lots of people use alfalfa sprouts on salads and sandwiches.
The one I remember doesn't sprout is flax seed...it just turns into a gloopy mess thanks to the mucilagenous compounds (some vegans use ground flax as egg replacer to give you an idea).
Different seeds require different soaking...
See the dark grey "handles" in the picture? They flip in like that so you can stack baskets.
I am trying out pond planting baskets for my fodder since they are designed to allow water in (and out) but keep soil in, so I figured they would work for seeds. Will post results once I have them.
Did you use oats in your initial trials? Apparently they are one of the most difficult to grow to fodder for some people. I tried them using racehorse oats...it took forever to sprout and two weeks to grow to fodder.
I did this a few weeks ago using racing horse oats. Just put them in a colander in my double sink, gave them a good rinse twice daily, and then when they grew enough greenery I trimmed it down and gave it to my chicks in the brooder for some entertainment. At first they were just having fun...
