I have found it nearly impossible to find large Flock Blocks in any of my local feed stores. The only ones I have found are brick size, and they won't last long with our 14 hens. I need them to keep the girls busy when they can't get outside of the run due to foul weather. The large blocks I have found are game blocks which seem fine but cost $20 each and frankly, we can't really afford the extra cost. I have found many recipes for home made "Flock Blocks" on the internet. Many call for wheat germ. I have about 15 lbs of wheat bran left over from a bag that I bought to make bran mashes for my horse this winter. I would like to use this in the recipe instead of the wheat germ. I know that feeding too much wheat bran to horses can cause calcium and phosphorus imbalances. Is it safe to feed it to my hens? Also, I have some old stale fig bars that I was about to throw away, but was wondering if they would be safe to feed my hens as well.
