I was reading up on stevia today, figuring out how to use the bumper crop of leaves I have. I've never used it other than picking a few leaves off to chew on. I figured, I'm drying a bunch of other herbs today, I'll see what I can do with stevia leaves. I found this on wikipedia: Possible treatment of osteoporosis has been suggested by the patent application claim that eggshell breakage can be reduced by 75% by adding a small percentage of stevia leaf powder to chicken feed. It has also been suggested that pigs fed stevia extract had twice as much calcium content in their meat, but these claims have been unverified. Has anyone here fed their chickens stevia extract? Or leaves, or noticed any effects one way or another from their chickens getting into a stevia plant in the garden?
