I found one of my hens, in the nesting box, standing up. She was panting and making straining noises, like she couldn't quite pass the egg. I have never seen her stand while trying to lay and egg. Anyways, I was quite worried about her. She was straining for a good 20 minutes after I got there. Then finally, plop, the egg dropped, and boy was it a whopper. When she was done, it seemed like she was walking a bit slow as it had caused some pain. She was completely red in that region also. This is the hen that lays double yolkers quite often. This time she might have actually made a triple. Needless to say, I tossed out some treats for her. Poor thing.
