one of my birds is pecking at eggs. sometimes it just strikes it once and puts a dent in it, broken shell. the other morning I found a shell that was 2/3rds missing, yoke and white gone. I have a light in the coop, comes on at 2am. I check the box before work at 4:30 am. that is when I find a broken shell. that time in the morning normally a rir or 2 or rir and bo has laid a egg. I think I have to add a video camera to find out who it is. 2. I keep adding straw to the boxes, they drag it out and start to build under the nesting box board and I have been finding eggs on the floor and run from some of the bantams. I don't know whats going on lately but they are going nuts on me. what to do what to do?
