I started to do fermented feeds, but that somehow never quite worked out, so I gave up and just went with soaked feeds, which I typically soak the night before I feed them.

Part of it is my way of using up the chick starter crumbles, since soaking the high protein feed makes it okay for everyone, and it'd been a good way of helping to keep my birds hydrated during our ridiculously hot weather this summer.

I add a large scoop of chia seeds, and two or three heaping spoonsful of diatomaceous earth for added minerals, along with a generous swig of organic apple cider vinegar, before mixing it all well with clean filtered water. Our girls have been laying better, and everyone has been happier overall, since I started doing so.
