Hens go broody when you don’t want them to… and won’t go broody when you do. 
I have three Khaki Campbell ducks I love them! They started laying on Sunday I have two hens and one drake. How long can the eggs go before I collect them to eat? I was waiting to see if they would sit on their eggs because the drake keeps mating with them. But every thing I read says they won't because they are not the motherly type, what should I do?
