Greetings, everyone I think things are going pretty well, but decided to ask for feedback about what I suspect is par for the course with a flock just beginning to lay. They are eighteen weeks old, one has been laying for two weeks, another couple have gotten on board during that time, too. They lay somewhere around 5 in the morning, or so. But once last week, and again today, someone (they do this when I am not looking) lays a shell-less egg in the late afternoon, just wherever she happens to be. Don't know if it's the same duck. My current thoughts are, it's a sign of someone getting ready to lay but not quite there yet, and possibly with all the mounting going on, perhaps an egg gets pushed out before it gets its shell. Here are bits of information that may be helpful: They get free choice oyster shell, available at all times except overnight (same as their food - water is available 24/7). They have grower/maintenance pellets plus a handful of cat kibble per six cups pellets (approximate). All females in the flock. Treats include salad (lettuce, dandelion, jewelweed, comfrey), peas (once every day or two - a few cups for all eleven), slugs as available They are in a duck yard most of the time right now, so they get whatever crawls or flies in, and whatever I toss in. Temperatures five days ago were in the forties at night, seventies daytime, yesterday mid90s, today about 97 F. It may have been a warm (85F) day the first time an egg without a shell came out). They are runners, weighing just barely 3 pounds or so each, some variety in size although all are the same age.
