Since your questions are address to me so I shall try my best to give my opinions which obviously differ from some SIFU and there are what I truly feel.
From my humble opinion which is not a favourite one. I believe that if I am a swiftlet, I will go for a dark place to have my nest as I have a advantage over my predators which most cannot find their way in darkness. Therefore, I shall feel safe. Althought, some do make their nests at the brighter area of the BH but bear in mind that the birds are wild and still have their natural instinct. I have seem birds building their nest on wire and hanging down from ceiling just like rocking baby bed. This is not normal to the birds so we do not just jump to conclusion that the birds have been domesticated. Remember that the birds migrate to the house to be safe because their caves have been destroy by human. Instinct tell them to migrate in order to save their species. Luckily, that at present, BHs allow them to breed or otherwise, when we wake up one day to see all swiftlets disappear from the world/
BHs need not be very dark but dark enough for the bird to feel safe and the wind should not be disturbing. Entrance size ???? no standard sizes and all depend on location and personally, I like bigger entrance to allow birds to fly in or out comfortably or otherwise if the opening is too narrow or difficult to enter, new birds may die trying to fly out during their maiden flight. I have seem a friend's BH has over 20 dead birds each time the bird fledged while trying to fly out. Sad story that over 100 birds have to die because of poor planing.
My personal opinions are that all issues are issues although some are bigger than others. If we cannot fulfilled it, we call that compromised. Like human, birds also have different behaviors and likings so even we are brighter or warmer or dryer or any error, we sometime get more that we expected. So, my recommendation is don't do anything if the going get better.....if you get my breeze.
Again, above are my own opinions and anyone may has different opinion and remember that I am of no high tech type......of rancher
