Yesterday our hen (mellow) was "talking" to the hen (jazzabelle) who was in the nesting box. They do not share the box (which is a divided 4'box) It seemed she wanted to go in and lay. My friend (and co chicken owner) picked her up and put her in the nest area, but she was in there a short time and did not lay an egg yesterday. She acted normal the rest of the day. Today however we noticed egg yolk, and white, and then the rest of the egg pass out her vent. Now the question is what should be be concerned about.
