Tonight all three chickens are back to sleeping nestled tightly, 3 in a row, on their roost. Apparently, what ever was disturbing the "zen of the pen" has been dispelled, and things are back to normal (note - we use the word "normal" in the relative sense, since there really is not very much that is normal about 3 chickens living down in the basement). Egg production is still down, though. We had been getting 3 eggs per day consistently until the girls started acting batty. Then we went a day or two with no eggs, and for the past two or three days we have been getting one, still perfectly respectable, egg each day when we get home from work and go down to check on the micro flock.
