I just recently started my flock and have 10 chickens ranging from 6 to 8 weeks old. Today I found a small ( just a little smaller than my 8 week old chicks) owl dead in the chicken run (pretty small fenced off area around the coop until they are a little older). My office is like 10 feet from the run and my door was open most of the day, so I think I would have heard a commotion if there was one, but it's a little weird none the less. Any ideas what might have happened? Should I be concerned?
