Fermenting. .. QED (quite easily done)
The is a fermenting for meat birds thread that is great - and it isn't limited to just meat birds.
Your birds will not waste it like dry, they consume less, and fermenting increases the digestible protein by a much as 3%.
After reading the fermenting thread of you have any questions don't hesitate to pm myself or @leahsmom - I'm sure she wouldn't mind and age has a better grasp on nutrition than most.
When I had less time, I though the idea a little more than fascinating. I am reconsidering it. There is more labor involved, but it doesn't seam substantial.
I do not buy into the exaggerated claims, or I should say skeptical.
The benefits that I would expect to see is less feed waste (a big deal), the probiotics (which I think they pick up grazing), and that the feed has already began to be digested. I could picture a feed reduction of 20%. If for no other reason than eliminating waste. I do not buy into the other claims, because they do not account for the changes that occur in the gut anyways. Could not say that there is not some truth to some of it, but am sure it goes the other way to. The truth is usually in the middle.
The hang ups I see, is the small amount of labor that would include cleaning the feeders every day. I do not think I want to leave that up to the ants and flies in the summer.
I expect that I will experiment with a group of birds and see if the labor is worth it, considering actual results. That is all that matters to me. If the birds are in fact better for it, and I save money, and do not spend too much time doing it . . . I am all for it.
A hang up for me is the quantity of pens. In the spring, I can have as many as 20 pens to feed. Mostly I have empty pens then to, but you get my dilemma. It is not as simple as a single flock.
