I normally replace my hens every year. I order chicks in Feb, hey are laying by July, and I sell the previous year's hens in August. I've noticed that whether they are hybrid egglaying breeds or heritage breeds, the number of eggs per day drops off after 18 months of age, or the second winter.

With hatchery bred hens, that is the case. I haven't seen a drop in production at all with my non-hatchery birds, but I'm likely to see it in their 3rd or 4th year. Now for those of you reading this and getting up about me saying that, - It's just a fact. Hatchery birds are bred for production, thus, it is focused on their first and possibly second cycle then dwindles fast.
Honestly it is up to you. Some people replace theirs every year because they want an egg a day, some people wait til the 3rd year when egg production halts almost to a stop (a common thing with most but not all hens)
I only replace my girls when I've got one of better quality to do so. I see no other reason. If she's laying poorly but makes up for it in quality, personality, or the worth of her eggs, she's staying.
There are different management methods. If you have egg customers and require X number of eggs from X number of hens, and the lay rate is X, etc.....
Our program is to rotate in young pullets every six months. I brood in spring and fall. This means the hens are never all the same age. When laying falls, whenever that point is, 2 years 3 years, etc, they can be removed. Normally, I remove hens at 2 years and know a family that has need of them. Whether they choose to keep them for another year's egg production, at a lower rate, or feed their large family with them, is up to them.
