I sent my poor DD out to collect eggs and she came back in screaming. My first thought was she may have been bitten by a snake. It turns out that all 5 of my young (2-3 months old) polish were lying decapitated in thier run. There are no animal tracks in the dirt. There were blood drops on the top of the fence. They were all in a group. But my three adult polish in the same run were unharmed. Is there a flying predator that would do this? the heads are completely missing.
