Ohhh please tell me about your process for this! I've sprouted some hard red wheat for them and they devoured it in minutes. I can't image feeding it to them as primary source of their diet simply due to the effort put in. How do you do this? Is it more cost effective? And what is it you are sprouting?
Yes, it is more work, but well worth it to us and I don't find it that hard really. I sprout in 5-gal buckets, one day's worth of feed in one bucket. I just soak the grain for 2-4 hours then drain, and rinse once a day, until the sprouts are as grown as a person would want to eat, no longer, typically 3-5 days. So, once a day, everyday, I start a new bucket soaking, rinse the others, and feed the oldest.
I know that most people would not consider what we feed to be sufficiently balanced, but we've been doing it for over a decade now and our chickens are doing so much better than they ever did on the commercial feed, so I know it works. When we started we just fed barley sprouts, that's it, nothing else. We had 7, 6yr old sex-links, that hadn't layed for several years, we just fed them barley sprouts, nothing else, no free ranging and it took about a year for them to start laying again. We got 4 eggs a day from them during their 7th year, and one of those hens lived to almost 13yrs. We have changed some things over time, mostly we added bentonite clay and kelp, however we moved and barley is too expensive here, so we switch to wheat instead, which I do not find to be as good, so we had to add alfalfa leaves, too.
In short, what we feed is: sprouted wheat, alfalfa leaves, bentonite clay, kelp, and we leave ground limestone out, free feed, for extra calcium. The alfalfa is just what falls from our hay bales which I gather and add.
We figured it out one time, and it costs us about half what it would cost us to feed commercial feed, so yes, it saves us a lot.
Free ranging can be very helpful, but when we started, we didn't have that option, sprouting can help make-up for that. Anyhow, there are many different right ways to feed, this is just what works for us.
