My duck eggs have been getting very thin. I removed spinach and kale from the diet. I'm using Layena Plus and some cracked corn. My birds have lots of outdoor space and catch bugs and work the dirt and sometimes puddles. Lots of fresh water. Lettuce, shredded carrots, peas, sweet corn, parsley,dandelion, and other mixed greens. Also some of my ducks do not seem to be growing in their new wing feathers correctly. Any ideas would be appreciated, Jean
Some pics would be nice to go on? Do you also provide oyster shell? and even sometimes with heavy layers we will need to provide some calcium citrate at times since their bodies can get depleted after a while. What breed or breeds are you talking about? Age?
