The weakness is the auto-opening mechanism then; your lovely ply coops in Catalonia would face the same issue if their doors were opened automatically by a string (but in those days you were on hand to open them in person of course, so no string on the door). Only the design that BDutch was recommending would solve that problem, and yes, that wouldn't work with a Nestera.I need to be able to rely on the pop door to open the coop in the morning. I've had the string chewed through twice
As for rats and weasels, all I can say is that they have not, to my knowledge, tried to gain access to the coops here - and I have seen both, though the weasel only once, so they do live round here. I assume the vent has been designed with them (and any other UK predator) in mind. To give some idea of scale to those unfamiliar with them, the vent cover has a diameter of 19cm / 7 1/2". Should something try to hang on to - what exactly? - while chewing away a baffle to enable them to get past, I would expect the chicken roosting nearest to give it a very swift and hard peck. For the compact design and the roost height and position means that a large fowl will very likely be positioned right there, looking straight out that vent. A rat or weasel finger would make a great snack
.My birds would not take an attempted home invasion lying down; they would attack whatever bit of a would-be intruder came in range.
On the mites, the Solway has more joins and hiding places than the Nestera, and I think you've made it worse with your modifications. That is very obvious at the vent: it is covered with mite eggs (those white dots). Every screw and new bit added has offered homes to parasites. The smooth continuous sheets of a Nestera are much more difficult for mites to infest. And the complete disassembly allows for a cleaning much more thorough than possible on a Solway.
I agree entirely with your remarks on space.
Correct. It's not rigid though. Unpredictability is a deliberate predator avoidance tactic. And anyone who comes looking for handouts gets them.if I've understood correctly you feed your chickens twice a day for a limited period of time and take the feed up after.

you are right, I did not get the point.
