I got these ducks from Tractor Supply. Was told I bought 3 Pekin. 2 of the ducks are Pekin but the middle one is not. What is she/he? Also bought what I was told was 3 Khaki Campbell ducks. Is the dark duck pictured a Campbell and can you tell if its and male or female? (First pic) Second pic is a better pic of all ducks for reference. Any help would be appreciated. All ducks are about 5ish weeks old.
