I have a total of 18 laying hens, they range from white leghorns, road island red, and new Hampshire red. I added 8 more chicks this spring. I put them in with the older 10 hens in June. Since around that time my older hens which at the time were only 16 months old, and now are 19 months old are only laying 1 to 2 eggs a day. The young ones are laying an egg a day. there are some days I don't even get an egg from the old ones. I thought maybe they are eating them but during the weekend I get down to the coop and pick early and still only 8 if I am lucky 10. every once in while I see that one has been eaten as I see what is left of the egg white in the nesting box. I am to the point that I am tired of feeding these birds with no egg production. The Road Island Red is a big bird and eats a lot. The have plenty of food given to them, I have a hanging feeder that I add food to when needed. the get some corn as a treat maybe every 3 days or so. Get plenty of water and the get outside time. The coop is 10'x30' and there run outside is 25'x15'. I tried to read some of the older posts on here and it is a little confusing as 95% of the replies to the post about hens not laying are people saying they have the same issue. I know they drop off in production as they age but not they don't stop at 13 months of age. this has been going on now for 5 full months. I have a light on a timer already so that isn't the issue. Any insight would be much appreciated. Thank you!
