Sorry it soo long since I replyed. 65 posts since I was on yesterday. The FF is extremely high in probodics,and the post i was talking about, the OT is bring back her flock from the brink of death. I could not believe the pictures after only 3 weeks on the FF. It's also used a lot for hogs from what I've read-1st time I have heard of it with equines, it was not until I was reading this,
https://www.backyardchickens.com/forum/newestpost/709707, that I found out I also works on chickens. when I was reading here at E TN that japs sometimes starve because the feed was too large, I thought that It would be a perfect solution to the problem, that combined with all those lovely probodics formed at the same time--sounds like kefir for birds.
