I have been hatching out small numbers of Indian Runner ducklings over the last 6 weeks..Sold a few already- and there is a lady coming to buy some tomorrow. I told her she can choose out of the ten I have here- and she said she isnt too fussed about colour or age- but wants a male and a female. Most are at an age I can sex by the voice now. The five I already sold were 1 male and 4 females. But my dilemma is..... I think all ten I have here now are female. I hear definite loud quacking voices from 8 of them- and going by the colouring of the other two- they are also females...So if I am correct - So far from 15 ducklings hatched I had 1 male and 14 female. Anyone else ever had the fortune to have a male to female ratio like that before???
