I only found one other person asking about juniper berries and they had not been answered, so... Part of our chicken yard is underneath some old cedar trees so I am wondering if they berries and the needles that fall on the ground can have any detrimental effect. They don't seem to be eating them, but I can't be sure. One chicken has gone to laying every other day and is sometimes having bumpy shells, and this morning I found a really weird poop that was so large you'd think it came from a dog. It looked like there might be a little blood on the white part but I can't be sure if that's what it was.
