OK dumb question lol but can they control when they lay?
I don't know. I'm relatively new here so defer to others. Of my eight three-year-old chickens, only four lay eggs and when they do is totally random. My Silkie has laid maybe three eggs in her entire lifetime and there's at least one I've never seen in the layer box. I don't know if you can "train" them to lay earlier, but that might be worth looking into.
