first a snake getting chicks and now something unknown has gotten 3 of my favorite "old" hens.... if they were Bobwhites i'd figure they went after each other ...BUT.. these are coturnix that have lived together since hatch over a year ago. AND there's no blood on anyone's beaks . Something is getting hold of my hens in 1 cage through 1/2" hardware cloth and chewing holes in their bodies just about where the primary wing feather tips are. it's only the 1 cage . Any ideas on what it may be and what i could do to protect them in the future would be GREATLY appreciated! i moved remaining birds from that cage but if whatever it is decides to go after another cage ...?
