I have two easter Eggers that are about 5 months old. They have been laying consistently for 4 weeks now. I get atleast 1 every 2 days. I changed their bedding on Saturday and now as of Wednesday I have had no eggs from them. They are acting fine and eating good. The temperature has dropped some here in Cincinnati but not a ton. My 2 leg horns are still laying 2 a day. Should I be concerned or what should I do?
