Until what age do hens lay eggs? When does the productivity go down? I am just curious because most of my hens are still rather young. The RIR has just recently started laying and I get about 5 eggs from her per week. My Delawares are about 20 weeks old now and not laying yet. I just got an egg from the other Polish girl yesterday (her 1st ever). The others are not laying currently (i.e. Silkie, the second Polish and the OEGBs). Thanks!!!
