That's good to know. I'm a worrier about my flock. I just started using mother vinegar, but offer it as a choice next to their water. So far I haven't noticed any difference, but I think that the ferment will make a big difference and am excited to give it a try. My flock is not for meat, just eggs, but from what I am reading here, it sounds like the fermented feed is good for everyone. 
Thanks again!

Thanks again!
