I've fermented feed in the last just for fun to and to give it a try. I did a butt load of research before and could never find a clear answer to this question. After watching videos and reading for hours I'm still confused. I'm using the double bucket with holes drilled in the inner bucket for easy straining. My first question is should the water remain over the feed the whole time its fermenting or after the 2nd day or so is it ok if it's all absorbed? I've found that to have conflicting answers. When I did it before I just used a single bucket and a wire strainer and cheesecloth to get the water out. And my other question is the last time I seemed to get this white film on the top of the water.... what is that? It still smelled fine and they still gobbled it up. For the most part my hens seem to know if food is bad and wont eat it. Hopefully someone can give me a clear answer. Thank you in advance.
