I have to take that one on the chin. (googled flax seed benefits) It will be good for them. How much is the question now right. I use the 10% rule for just about everything . 10% of the daily intake of food. Like if you feed 10 pounds of chicken feed 1 pound of flax seed is ok. With your 17% protein feed @ 10 lbs and 10% of each grain you mentioned flax, barley, BOSS you protein level would be around 17.6 % . So you will be ok. Thanks mickey Heinz is ok but I do like Krogers and here they carry a brand called Spectrum it is two shelves or so above the Braggs and it is cheaper than braggs. I use it and it seems to work rather good.OK Didn't think the fat content through first, Maybe just won't use the flax. Glad I asked first. Thanx. Just in case someone maybe havin trouble finding un pasteurized apple cider vinegar, yes my Kroger said they had Braggs but also found it at wal-mart but it's Heinz.
I'm glad you ask too we all learned something. I'm going to see what 100 pound of flax seed cost from the feed mill.
