Do hens like the coop darker for laying eggs?

[cheepsforkeeps]

Does anyone have experience with light verses dark for the hens laying eggs in the coop? A friend of mine had mentioned that when they built a new coop and run her husband added a stain glass window and some of the hens started laying on the ground in darker corners. Has anyone got advice on this?

IMO, yes they like a nice dark secluded place.
