Did you check their bellies to see if they are overweight?
As a dual purpose breed they tend to put on weight after their second year and if, just to give an example, they are being kept in a run with feed available at all times, they get too fat which leads to fewer and smaller eggs.
In case they get scratch, sprout it, best for them is sprouted barley. Up their carrot/vegetable intake and have them work for their feed.
It’s been a while since I have really put my hands on either one. They don’t look overweight to me but I know feathers can hide a lot. They do get free access to food 24 hours a day. I feed Kalmbach flock maker 20% protein oyster shells on the side, and some kitchen scraps(mostly vegetables). I tried catching them today but they outran me lol. Maybe I’ll get them off the roost tonight if the are on a roost close to the door.
