Ok, I have two hens that have quit laying, a barred rock and an ameraucana. My game hen is still laying 6 eggs a week. . . . They are living under the same conditions, extended light hours with a timer, same feed, same water. I was getting at least 5 eggs a week from the 2 that are not laying now..... What can be done to 'jump start' the hens into laying again ? I am stumped !
