It sounds like she's finding them and eating them, not being given straight to her. Chickens have something natural in them that given the right situation, can tell what is safe to eat and what's not. How you're saying she loves them makes me think that they are safe for her to eat.
Thank you for your reply. I help her forage.a lot she's my only bird. Today after I posted and had brought berries in for her she completely ignored them. Go figure!
