there not molting they are healthy they get plenty of layer mash and fresh water. they range from 6 months old to 1.5 yrs old. of the 23 birds i was getting a dozen a day and now this past week they went on strike . i put a light in the coop where the days are shorter here in the northeast. thinking that might help on at 4am and off at 7am 3 more hrs of light to bring it to 14 hrs they roost at 6pm.
