Mine started laying before 20 weeks. BUT mine were hatched the first few weeks of April. Now my hen is laying every day. How do Khaki Campbells out lay a Pekin if mine lays everyday????@holm25 -Do your ducklings lay the first fall or do they go through the winter first and then start in the spring? (that is what mine did they were mid june hatchlings last spring) How early have you had ducks start laying? I was just reading that some have had Pekins start at 16 weeks. That seems ridiculous. But got me wondering if these new ducklings might lay this year. I am also having trouble getting the older ducks to behave with the younger ones. They are downright nasty. Should I just forget trying to get them to integrate and make separate areas? The ducklings are 8 or 9 weeks old but are pretty close in size to the adults.
