We have beautiful eggs, nicely formed poo, and when utilized for meat birds ff significantly reduced odor, increased weights by 10% vs 'regular dry' chick starter (two brooders same hatch Cornish X from McMurray,loss 3 of 15 regular food vs 0 of 15 with ff). It's so easy that's why it's so hard lol! Big plastic bucket a few scoops of feed (crumble or pellet) a few glugs of ACv with the mother (found Braggs at all health stores)- water to top of this feed- cover wait a day stir the mix should smell a bit vinagery for a few days and you'll see bubbles, wait a few days to allow fermentation (usually recommended 3 to 5 days to allow for release of protiens/probiotics). Begin feeding my girls didn't like the way it "stuck" to their beaks but loved it, so they kept comming back for more. Of course my girls don't do plain yougert since it's too sticky, but for ff it's all good. Also can add just about any scratch/Boss etc. I l've been adding a few sprinkles of the brewers yeast each time I add more crumble to the bucket. only problem is here in La. it's so humid I had to vent mine to prevent mold, but if you STIR when you feed or add crumble that should do it IMHO. Thank you again Bee and Kuntrygirl
