Let me start at what I think might be the beginning. As soon as I put a heat lamp on my hens this winter, I started having a problem with eggs being eaten. It is one hen doing it, I can tell, because it's always in the same corner of the same box. I would get two good eggs, and one shell broken in half, with most of the inside in the hay underneath it. I removed the light and the eggs stopped being eaten (except for tonight, but I'll get to that). However, the eggs weren't intact. There would always be a hole, or a crack, with none of the inside having been eaten. Some days the egg would be falling out, other days there would just be a small hole and the inner membrane would be fine. I work all day, so I can't do any spying to see who is laying in that box, or figure out what might be happening. I plan on doing some sleuthing this weekend though. The last three days, there was no egg from one of the chickens, and no evidence of there having been an egg laid. The same chicken who has been cracking eggs was still up to her deeds, so I know it is another hen who is not laying. But this morning when I let the ladies out, I saw three perfect eggs lying far from the boxes, underneath their perch! I gathered them up and took them inside. Tonight, I went out to collect my eggs, and found one intact egg, one mostly eaten egg, and no third egg. I used the flashlight to check around the coop and then the yard for a hidden egg, but didn't find anything. So, what is going on? I obviously have an egg eater who will most likely have to be eaten if all the good suggestions I found on this forum don't work. But why is hen #2 laying outside the boxes? She's been laying inside them since they started a few months ago. Is she hiding her eggs from the culprit? Is she going broody? Is she just unhappy with her boxes? Thanks in advance for reading four paragraphs (if you did!) and for any answers you can give me.
