Need help naming these ducks. Don't know which are males or females yet, but need some ideas, please. 1,2,3,and 4 are about 4 days old. A, b, and c are 3 1/2 weeks. (Another note, just in case: 1 and 2 are either white crested or crested pekins, 3 is an Ancona (we believe), 4 and a are rouens (we just realized this today, thought they were mallards), b is a Black Swedish, and c is a White Pekin).
