I have 4 pekin ducks, 3 drakes and one hen. we want to get 2 more hens to stop the drakes from fighting. my mom wants to hatch some of the eggs for her friend. if we were to hatch them, could i take two of the girl babies and have them be our hens (once they grow up of course.) we won't know who the father is but we won't be hatching any more eggs, so would it be wrong to put the babies with their possible parents to be their mates? would their parents know that they are their parents?
