Hi everyone. We have two female khaki ducks that we got in the spring. We wanted to hatch ducklings in the spring so we bought another female and a male about a month ago. So far I haven't seen the male try to breed any of the females and when I crack open the eggs to use, they don't have the big white bullseye like the fertilized chicken eggs. Do they stop mating when it gets cold or do they keep on breeding all year? They're all full grown khakis and the male is clearly a male lol thanks for the input
