Well, I would be quite surprised if they lived 4-5 years. Mine often times go around 2.5 -3.5 years. But that is a huge give or take, and you can loose them at any time, a lot of chickens are not real long lived. Some people get so upset, I wonder if chickens are a good hobby for them.
I am glad you did not fill your coop the first year, but am hesitant to ask, so many pre-fab coops say they hold 6 birds...that 6 birds become a red flag...so what are the dimensions of your coop? If it is a prefab coop, thank goodness you don't have 6 chickens, and disregard the rest of this advice.
I would add 2-3 chicks each year... or at least, every other year. Your flock gets used to adding new birds, and very often you will loose a couple over the year. I keep a flock, and the birds in the flock, come and go.
If you have a pre fab coop, do not add any more birds, until your current birds are gone, they just do not have much room for adding birds.
