I'll see if I can get a copy. I can't read the article on the site.I can't find the article I had previously read, but I read it 5-6 years ago when I first started with chickens. It mentioned increasing risk of egg binding (which scared me - that's why I remember that part). As previously said, it was an article, not a scientific study.
However, this clinical study from 2019 does mention stress (2nd most prevalent among other things) as a cause of cloacal egg binding/dystocia:

However, I agree that stress takes a massive toll on a chickens health.
