Are all greens safe for chickens?

[RickaRoo]

We have radish greens that we wanted to feed to our chicks but weren't sure if that was safe for our hens. Are all greens safe for chicks? If not, which should we avoid? Thanks!

I would avoid giving them anything from the nightshade family, but in my experience they seem to know what they can eat and what they can't (styrofoam excluded), and won't eat it if its something that isn't good for them.

Radish greens are fine.

Unless they are starving I've never known a chicken to eat any plant that was toxic to them. Most of them taste bad.
