Grim reaper kills all farm animals like chickens and lamas

My chicken and lamas keep dying off old age even tho I have the option aging off in the menu. I play on different families so everytime I switch lots the grim reaper is there to kill all my animals... I can't seem to fix it. Does anyone know a solution? I play on ps5. I have the feeling that i can't use the pack cottage living anymore... waste of my money.
