Ate glass??

[Adorableyardcare]

I think my chickens ate glass! I haven’t ever seen this in my chickens poop before they’re about a year old and I recently just cleaned up my backyard from debris that included glass and possibly plexiglass and lots of plastic and right after cleaning up they started pooping little hard sea glass looking things.
please help I’m not sure what to do about this or what it even is for sure

Is that what was cleaned out of the birds area or the yard ?

No the pieces were much bigger than that. I’m just wondering if they had eaten it and used it as grit

Welcome to BYC! If they start acting strange bring them to the vet. Otherwise double check the yard 4 glass and give them grit

Thank you! Yeah they’re all acting fine so not too worried about it yet. More worried about my limping chicken right now.
