I didn't know anything ate eggplant
My chicken coop sets under a hackberry tree. They loved the tender leaves the tree happened to drop in the spring; to the point that I tried them, somewhat of a mustard green taste, not bad.
yes, i can google the refute too. You can't eat enough spinach to deplete calcium, or at least i know i can't
don't believe everything on the internet. and eat your spinach, it's good for you.
bread, pasta, and meat seem to be the favorites in the leftovers from the table. I fed a tub of ricotta cheese to them once; they loved that, preened each others face for the remaining bits.
Not so interested in green stuff other than spinach, but mine free range some so green isn't so rare.
