i've posted a lot of threads about this before. another one of my male ducks died. to replace the 2 males ive lost im going to order 2 more females. i now have 3 mallard/pekin cross 2 female, 1 male. i am now ordering 1 pair (1 male and 1 female) of buff orpington ducks, 1 pair of khaki campbells, 1 pair of rouen ducks, 4 female pekins, 2 cayuga females. i also was going to order 2 females of a different breed. that would make 12 females and 4 males. first the 1:3 ratio is safe right. and what should my last breed that im getting 2 females of be. and if i coudnt get 2 females of another breed would my 4:10 male to female ratio be okay.
