5 hens = 5 eggs per day, that is 1 egg per day per hen.
There are caveats: Hens take 26 hours to lay one egg. So, you eventually will get a day skipped.
There has to be enough light per day (about 16 hours). They have to be healthy.
Depending on the hen or the environment, if they get upset, like you change their cage, they might skip a day or two or a week...
My hens did go through "menopause" when they turned 2 1/2 years. They had artificial light, so they laid from 6 weeks on everyday for 2 1/2 years. I was happy with what they gave.
