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.
