One of my b/o hens looked a little weird earlier, all puffed up. So, I picked her up and put her into into her nesting box, figuring she had to lay. Well, she jumped out right away and went back outside. Once out there, I spied on her again and noticed the same behavior, only this time she was straining. At this point, one of my other hens runs over, circling her again and again. She looked like she knew what was about to happen. Anyway, the original hen drops a soft shelled egg and my other hen is there to snatch up the goods. I haven't been getting as many eggs lately and now I know why. They get oyster shells daily and laying pellets, so all should be ok. Although I have to admit they don't get wormed. But I do check them regularly for mites and pests. Hmmmm interesting.
