Hi all- I have 4 WHs, two years old last August. From 6 months old 'til this late Summer/early Fall, they laid darn near an egg a day apiece; then they started molting and have really gone down in egg production. Now it's none to one a day- rarely, two a day. I feel like they've earned a rest! So I haven't supplemented their light as I have with the chickens. But I also am noticing that there's a broken egg in the nestbox quite often. I feed them (& have throughout) Layena and free choice oyster shell (same as the chickens, who still have nice strong eggs). All of them range around during the day, eating green stuff and bugs; but that's been consistent all their lives. They all have food and water available in their night-time coops/runs. The ducks even have shell and grit available. Some duck egg buyers were a bit put-off by how hard the eggshells were last year, but that's not the case any more, even with the ones that don't break. My questions are: Will they ever go back to that prolific egg laying? And, is it normal for eggshells to get less strong as the duck gets older? Is it just because of molting? (I gather that producing all those feathers takes a bit of effort....) Should I change their feed? And, should I supplement their light, more for their health than for more eggs? In other words, does less light affect the shell-making process? I'm a bit worried about one of the eggs breaking INSIDE the duck. (Should I worry about that?) Lots of questions- thanks, in advance, for your help!
