This is a great article about more natural forms of calcium they can get in some other foods, and who knew chia? I use a small amount when fermenting grains for all the probiotics but didn't realize calcium.
I think you should also include oyster shell though as it's easy and simpler for some and is also a way to provide calcium to our chickens. It is all natural too, though some don't realize that.
