Dcs went out this morning to let out the hens - did the large egglayers fine, then went to the stable to put our pet cockerel and our 3 bantam hens out.
First I knew there was a problem was hysterical screaming from dd1. 2 of the hens were lying dead with no heads or wings and the third has completely disappeared.

They were shut in an indoor puppy cage in the stable where the cockerel has lived at night for the last 3 years. The hens only moved in with him a week ago as they were being picked on by the bigger girls. They all went in their own run outside during the day. The irony is they are brought in at night as their day run isn't particularly fox proof.
Its not a fox cos he wouldn't be able to get through the cage so its got to be something smaller. Dh says stoat or weasel or similar as the kill pattern fits.
How do I stop the little buggers getting any of the other girls? The cockerel has moved into the utility room tonight in the cat basket.
Any advice welcome
