Last night something dug under my chicken run and massicared 15, 3 month old chickens and 3, 3 month old duckings, 2 duckings were too badly damaged so had to get rid, 1 ducks got a broken wing and were having it amputated today, 1 duckling has bad mauling on its back which should repair.1 chick is untouched. There was 2 holes dug under the coop, all birds were just randamley maulled to death mainly on there backs, not one was half eatten, would this be a fox or a domestic dog? I thought foxes ripped there heads off an pull there feathers off? Theres wasnt many feathers laying about either. What do you guys think it was. It must have happened around 1-2 am as i went out to them at 5.30am and they had gone fairly stiff. Please advise.
