How long have you had them?Help advice needed! I've had 3 hens died in two days, all xcross breed frizzle and austrolps. Sisters. First all looked normal and healthy, dead in pen in morning. Other was dead by night. Next one was nearly dead with her neck twisted around couldn't move.. then died.. I don't think it was poisoned. Could it be a genic disorder? No sighns of blood or trama?
