Ommygoodness!! What a terrible couple days you’ve had! Yes that is the calling card of a raccoon. They reach through the wire and grab the headsI just went out to the coop, to let my birds out, and I saw my cute little lemon barred hen Phoebe's feathers about, it didn't look good, then I found her body, head missing. Raccoon? I didn't know she was still out when door was closed last night.
