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.
With each year you find strength you didn't know you had, will you only dreamed of, and new ambition you must see through. You go to bed just wiped out, and by some miracle, morning brings the renewal you need (often with the help of some ibuprofen) to start again! One nice thing about aging is the appreciation you gain for things once minor, small increments of accomplishment, and kindnesses repeated day after day you never noticed before.
