Here's the scoop, as best as I can remember. We got 4 ducks at the end of March this year, 2 females (1 rouen, Penelope and one Pekin, Daisy), and 2 males (same breed as the females). I ended up having to remove one of the males because he was beating the other male up and drawing blood. Seeing as we really enjoy the eggs, I found a W/H female (Cami) sometime in May, she was supposed to be close to 4 months old when I got her. I was getting an egg a day on average from the Rouen and Pekin, until a few weeks after we got Cami. Started seeing a ton of feathers in the pen, and assumed they were just molting and egg production would resume in a few weeks. NOTHING! I'm pretty sure my WH should be laying at this point in her life, and the other should be as well. the days are shorter now so maybe I need a light in the coop to extend the light to 14-16 hours/day? I feed them chicken layer pellets. I have put crushed oyster shell out before, but they didn't touch it. Please help!
