I think it was during the day. She was sitting behind a feed storage can inside my coop, on a golf ball. The coop has chickens and now 3 pigeons. She was nesting on the floor. The coop door is open during the day. The golf ball had moved 8 inches, so I'm thinking that she was taken off the nest. I don't have hawks. I have crows . I have not seen any animal activity out there. I'm sure there are a few rats I haven't seen, I'm assuming. Any ideas?
