I came home from church last Sunday to find all 4 of my chickens dead or dieing. We decided they must have gotten into something and were poisoned. Yesterday I was sitting in the yard and noticed the Juniper bushes had berries. The chicks were still contained in their box this time last year. I was wondering if anyone knew if Juniper berries or cedar tree berries or holy tree berries were poisonous to the chickens?
