Hmm I’m not sure then! Just out of curiosity, why do you want to eliminate the egg laying? Do you think it’s causing the crazy behavior? The broodiness? If anything, laying made my birds calmer. And most of mine never go broody. Though that’s chickens but still. I have Cots too. All were flighty until after they started laying and laying calmed them down. So I can’t imagine stopping it would make yours any calmer. It might just be their particular personalities.They do have the best dust bath in the world and love using it.
Their behavior really is no different than almost any fowl. It's just that any fowl I previously had were to lay eggs. I never even thought about stopping egg laying with fowl. I know you cannot eliminate it, but I am sure that it can be mitigated.
