Hello, my chickens died in a 100% enclosed cage... Here is the design: A chainlink fence going 3 ft in the ground and 2 above. A door but its not 'easy' to get in. But.... What's been happening is strange it's just a hole throught the chickens, usually where the head was... Please Help Also I live in CA (California). Ontop is a tarp but they're no ways a raccoon could've got in unless it was a VERY small one.
