My little Lakenvelder was acting strange this morning. She had her tail bent down, wouln't eat and was hiding. I thought she was about to lay. I checked on her a half hour later to find she was in the nest box, standing up and laying a Rubber shelled egg. I took the egg. A half hour later I go back out to the coop to find she layed a yolk. I cleaned it up. It has been an hour since her "yolk egg" was layed but she keeps going back in the nest box and acts like she's going to lay again. I gave her some rasberries yesterday does that have anything to do with it?
