About 4 weeks ago I picked up 6 ready to lays, my first hens. It was love at first sight, and the day after bringing them home I had 2 eggs. It took about 3 weeks before I was collecting 6 eggs a day. My concern is, I have found 2 eggs in the course of the 4 weeks "smashed" and yesterday one with the top "poked" but the membrane still intact. I thought the first one, maybe the shell wasn't hard I know laying the perfect eggs takes time and practice, but now I'm wondering if one of the hens is braking them. Why would they do this and what can I do about it?
