Someone on the other FF thread~the one I started~did the math on it. She keeps meticulous accounting records on her farm expenditures. I can't remember her exact figures, nor did I save her post, but she had been spending 2K+ on feed each year, but that number was down to around $1200+, if my memory is serving me well. It worked out to little over half the amount she was spending before FF. Her numbers were pretty impressive.
Thanks Bee. I'm not surprised at all. I'd do a trial, but I already believe that FF is the way to go, so I'd be hard pressed to feed a control group non-FF when I know they'd suffer because of it. If my production ever gets to the point that I can justify it, I'll do it. It'll probably be with quail, as they finish in 8 weeks, so it'll be a quick comparison. I'll see if I can set it up this summer, but I'm on a VERY small lot downtown in a city, so I'll have to play it by ear.
