Yes! I only recently discovered this was a thing after cows suddenly started getting bird flu and someone said “maybe we shouldn’t have been feeding them bird shit?”
Don’t believe me? Search for “broiler litter” or “poultry litter” and “cow feedstock.”
I caught some flak because my husband is 8 years younger. I reminded my family that they let my mom get married off at 14, and nobody brings it up anymore. Tennessee (USA), if you’re wondering.
