I have 11 hens, and 5 point of lay pullets. I have 2 duck hens. I get 2 duck eggs every single day. I get 2-3 chicken eggs! Granted, my pullets are around 19 weeks and just getting old enough to start, but the older girls are 6-18 months and should be in their prime! If only I could get my family to like duck eggs as much as chicken eggs, I could get 3 more ducks and have no chickens and get just as many eggs as I am now. More if you count the fact that they are bigger, especially considering my best 2 layers out of my chickens at the moment are a silkie and a white leghorn (pullet, just started laying month ago and eggs are the same size as the silkies).
