I've got nine hens that eat about half of the day's eggs. They have enough space in the coop/run. They spend more than half of each day having fun running around the backyard. They have four nesting boxes. The boxes have plenty of fresh hay to lay on. I've put fake plastic eggs in the boxes. I've provided plenty of calcium (oyster), and have even mixed it into their feed/water. I started with four plymouth barred rocks and two reds, and added two "Americauna" and another plymouth last summer. The eating got bad this spring, so I don't know if the new ladies are part of the problem. I've put the four barred rocks in a separate space overnight until noon the next day for two days now, and of course now there are no eaten eggs in either spaces. But there are also only three or four eggs between the nine. So what does three year-old laying chicken taste like?
