Hi so I have 2 drakes I believe- a pekin and a mallard. They are 4 n half months old and I wanted to get them some girls lol and finna get 2 female ducks around the age of 4-5 months. A Rouen and a Pekin and I wanted to see if I should take any precautions or if they should get along just fine? I should probably separate the chickens for the start, cuz they live together but not sure how it would effect the new ducks. Any ideas?? thx!
