My three girls laid and egg a day since they were 19 weeks old UNTIL the very first first feather fell out to start the molt for the BO and SLW. Our BR hasn't dropped one feather yet and hasn't missed a day laying. At first I thought it was day length, but in hind site know they stopped the exact day their first feather fell out for the molt. I hope they start giving the occasional egg after they get their feathers back. One a day isn't cutting it around here!
