I was recently given 5 white call ducks. (2 Drakes, 3 hens) It appears that one of the hens has started laying. How many eggs does the average call duck hen lay in a season if you keep taking them? I'm just wondering because I'd like to incubate a few and also let one or two of the hens set on some when they're ready. Are they seasonal layers, or will they keep producing throughout the summer? Thanks in advance for any input.
