It's totally normal for hens to stop laying after a move. For the birds, eggs are about reproduction, so they stop under stress because that's not a good time to bring chicks into the world.
There are many things that can cause that kind of stress to be continual, including social dynamics within the flock, housing issues, predators stalking them, environmental noise, etc.
To be honest, the housing looks rather small for the size and number of hens. That one picture of the white hen under the coop kinda made me cringe.
So, if you don't mind me asking, what was your main motivation to get into chickens? Were you seeking a more humane source of eggs? Or just the eggs for eggs sake? Because they do cost less at the store than from keeping a backyard flock.
