Breeding of different species of ducks?

[Mommysongbird]

We have 7 ducks that will be going to my mother and father's house in a few more weeks, 2 are pekins and 5 are mallard. I believe all the mallards are MALE they have blue in their feathers. I am pretty sure that 1 of our pekins is a male and the other a female.

Will this cause a rukus with the mallards? Will they also try to mate with the pekin?

We have 2 pekins and 1 mallard that we are keeping, So far I am pretty sure the mallard is a male, has blue and white feathers in his wings. The guy at TS is pretty sure he gave us female pekins, but that is not a guarentee. Should we worry if one of the pekins is a female and the other a male with the male mallard?

well the mallard will mate your female pekin, having 2 males for 1 female is not good as they can drown her, seen it done

. mallards all look like females untill 8+ weeks of age, females have blue and white on wing tips, males have green heads after they get adult feathers 8-12 weeks

Thank you for the info. I am hoping that they are NOT males, but females. Although with straight runs, I know that won't usually happen.
