Does Milo eat pellets? I’m thinking that might also be a good way to get more protein into him. I’ve just had a consultation with Pamela Clark and she has recommended getting my flock eating high potency Harrisons for 6 months to right any deficiencies. That’s in addition to sprouts, veggies, fruit, nuts (not too many) and cooked grains and legumes, and some seed. Apparently Harrisons and Roudybush are the only ones she recommends.
Unfortunately Imgur has deleted all my pics, so for an updated version of sprouting (pics included!

), please see here:
