I've been considering tether for a while, look forward to reading your links.
Although there are some good general rules of thumb... EVERY situation is unique... flock dynamics, weather, cleaning schedule and so on. Regardless of what people like to think we MUST have, if it works for us... then it's that simple.
How many people say you can't keep roosters together that grew up apart? I've got a stag pen that says otherwise. 
Or you can't keep Silkies with large fowl or let them free range? Been doing that for years also, without issue. Or ya gotta lock your broody's away from the rest of the flock? Not! Though I did just recently move my bantams to their own pen to eliminate the worry of an accidental injury due to mating a LF rooster. Even when the rooster isn't "aggressive" toward the hens, they can still be a bit sloppy or excited and still learning to balance. Chunks of comb come up missing and such... and I KNOW my boy is pretty well behaved or guaranteed he would NOT be welcome here at almost 2 years old. Saddle doesn't do anything to protect the head area... which is where my issue crops up first. I control over mating issues, by keeping my boys separate and allowing for conjugal visits on MY schedule.Also note... NO amount of extra space or feeders will stop a chicken hell bent from going after another. Flare ups happen just as they do for anybody living together. I have PLENTY of space, and sometimes need to provide a "time out" for a relentless aggressor that got a feather stuck up their hiney.
If the time out doesn't correct the issue... it's off to freezer camp for a lesson they won't forget. 
Still as humanely as possible of course!I also want to note that an escape route may be less effective for a breeding age gal then it is for chicks. Reason being... it's not a simple peck and run away/chase. Very often the rooster has mounted before the hen can even realize it. So it will likely be over before she can even think to escape, most of the time. Or the other thing they chase until they get a hold of the neck feathers and then hold on tightly while getting in position to mount. Making it a look but don't touch set up... would totally work, in my EXPERIENCE. They still get to hang out through the fence but NO over mating or fear of injury. And depending on the age of your boy... they are SOOO much better once they've matured. Mine often mature to more than 1 year old before being allowed mating privileges. Huge difference between a horny teenager and young man that has gained some self control and had a chance to practice manners through the fence and had a chance for SOME of those raging hormones to settle down.
Good luck!
