Hi, my barred rock chickens are only laying one egg a day and there are 13 hens!! They are 11 months old and i don't get why! They were laying in march to may but they just stopped. Were feeding them egg laying pellets and they are penned up not free range...we tried that and it was an Easter egg hunt trying to find them! And they stopped when we were letting them free range...anyway what's your opinions or experience with doing this and not?? Thanks!!
