these are my first ducklings, they were raised by their muscovy broody mother and hatched naturally by her. For the first week we kept them inside in a brooder with their mother (no heat lamp) and now we've made a run for them outside and put them in there with their mother. I was just wondering when I can let them out to free range the whole yard? They will have their mother out there with them, but we also have a drake and other muscovy females, and chickens so will they be safe? (Currently 15 days old)
