I think it was the 'quiet hen' that laid today's egg. So I found it, picked it up, saw a dent, and felt around there. Soft!!!! They have laying feed, get free range, are as happy as can be (from what I can tell). All of the chickens had a dust bath yesterday. Today it's raining, and I opened the door and all the chickens jumped out, ignoring the fact that the scary human was right there. Was it just one of those off days, or should I consider adding calcium/shells/stuff?
