I have 25 hens ages 1 year and some will be 3 in May. Egg production?

The ones who are almost 3 years old seem not to be laying much I'm only averaging a dozen to 14 eggs a day. The big girls are not molting and are healthy nothing that I know has startled them.
The girls who are not laying much are red sex links.....( I will never buy sex links again I like wyndotts). I guess my question is......Is my laying problem the breed of the older hens are something I'm doing? The girls have so much room other chickens driving by get envious lol. They forage from dawn to dusk we feed mash from our feed mill and kalmbach layer feed daily we add each food to different feeders. I provide lots of fresh water. I follow dawgs advice on worming. I use a poop board and clean it, I have plenty of ventilation.
The girls are not molting.
Am I getting the correct amount of eggs for the number of chickens I own or is it the breed.

Oh I do have one older hen a wyndotte and she still lays she is almost 4.

Egg production is breed and age dependant. When I had a large flock of hens, mostly young (under a year old), I got on average 28 eggs from 56 hens daily. I had a assorted mutts and Lohman Brown hens. The Lohmans did not lay nearly as well as my mutts.

I think your low egg numbers could be due to the number of older ladies you have in your flock. But you said they are foraging, so it's possible they could be laying after all, but not where they are supposed to? Or you could be losing eggs to pests, such as mice or snakes.
