Preventing impacted crop?

[TTownChics]

I lost my fav hen last night to impacted crop. Everyone else seems fine. I opened her up and it was a big wad but the pieces didn't seem excessively long.
Now, i am paranoid about giving them stuff from my yard like I have been. Did i give too much? pieces too big? Pieces too small? I have been looking online at how to prevent crop impaction and there is contradicting info so I don't know what to do. I have had them a little over year and never had a problem before.

I am very sorry for your loss. I'm new to chickens too, so I'm curious what others have to say.

Do your chickens have free access to grit? What exactly did you give them? Just grass?

Yes, always have grit down. Usually, i dont give them a ton of grass but rather stuff around the yard like dead nettles and wild strawberries, not a whole lot of actual grass. We will throw in a handful here and there.
