Adding greenery to the duck run!

[Weeg]

I actually love the way buttercups look. My concern is, how do birds know when something is toxic? One of my birds ate tansy ragwort once, I actually saw her rip off a bite and swallow it. I go around pulling tansy for hours every year, but seeds blow in from neighbors. The vet put her on liver supplements for months.

Wow, I really don't know how they know, I guess I have never seen any of mine eat any. You never know though, better see then sorry.
That is crazy about your duck! Wow! Poor guy!
