I have 4 Call Drakes that have been mating with my big Hens. I ended up with one duckling that looks just like my Black Swedish Call. I presently have my 4 boys separated from the girls as they were chasing them and trying to mate all 9 of my Hens. They can be sexually aggressive it seems. My 5 week old small girl will not get introduced to them until mating season is over so that she does not get hurt.
