We had 3 ducks- 5 months old, all female, and have lost 2 in the past 2 weeks to an unknown predator ( daytime, and no trace of an attack- the ducks just vanish sometime between noon and 5;00 pm.) We are thinking possibly an eagle ? We have one left- these girls were hatched and hand raised. Should we bring in another female for our last little girl/? We are going to put her in the chicken yard for now. She is familiar with the silkies and sees them through the fence regularly. Will she integrate with them? Or does she need another duck ? Would a duck not raised by us do ok with her? So sad and want to do what's best for her.
