Avoid leghorns and LH X’s, I haven’t had too many issues with my production red breeds flying though. And their offspring crossed with a Ameraucana/Marans rooster are fairly ground dwelling, unless quite upset, and prolific layers of Olive eggs and fairly dark browns. Barred rocks maybe?
My Marans aren’t really flyers. But not as prolific as layers
