I have 7 red sex-link hens that are now 24 weeks old. At exactly 20 weeks, one of the girls started laying and has blessed me with an egg every single day since. The other 6 - zilch, nada. Just about the time the first girl started laying, cold weather descended (40-50's during the day, 20's at night). So I know the colder weather along with the shorter days slows down development, but it seems to have come to a full stop. The comb and wattles on most of the other girls are not fully developed and seem to have stopped growing completely. Have they missed a warm-weather window and won't produce eggs till spring, or do I just need to be a little more patient? Or am I possibly doing something wrong. Not sure I want to go the artificial light route. Many thanks for any help.
