Has anyone else freaked when checking out the link on the treats page for toxic plants? You go to this site that lists plants that are in abundance in my yard like buttercup, sheep sorrel, garlic, onions, amaranth, brassicas, chickweed etc. I mean, how does anyone ever let the chickens free range???? In a wet area like Northern California, buttercup abounds! There's no way I can get rid of it all. I'm hoping someone will write back who also has buttercup in their yard and has some info on this... I did cover the patch of buttercup in their pen with a sandbox and plan on pulling out the sheep sorrel today but yikes! I want to let my girls free range when they're old enough...
