I have a handful of chickens who have stopped laying completely. Would this happen for numerous reasons or is it only for a molt? They are under one-year-old and I see feathers around but not an excessive amount? WE are only getting 1 or 2 eggs a day (grrr) from our 9 chickens! Will those who stopped start up again this winter or are we going to be egg-hungry all winter! blah!
