We bought eight of our hens as adults. We're expanding the variety of their treats and are getting the funniest reactions. Yogurt has several of them wiping their beaks obsessively on the ground after each bite. New veggies are picked out and pulled apart systematically with a great deal of suspicion only to be competed for and devoured the next time they're offered. Apple cores look like big chunks of dirt after being dragged around the yard during the "investigation" process. What did yours do?
