Do I need an Improvement now or do I wait?

It's been two months of operation. It 's a very long and torturing 2 months with nothing to do but wait with anxiety. The number of tenants are too low, not up to my expectation.
It might due to the wrong season or it might due to the design of the house or etc.

I have to admit that when I designed this house, I didn't take into consideration of the wind factor.
My last visit, I found that the wind during this month is too strong, most birds will play at the South side of the building to avoid the strong North-East wind.
My partner suggested to open a small entry hole on South side to observe the birds' behavior. And as suspected, we found that the number of new birds fly into this new hole is more than those fly in from the open roof. But at night, the old birds still came back from the open roof entry hole. My bird house is in the foraging area, so there are birds around almost every day in the afternoon.

We also found that my partner birdhouse, same as mine, located in the East side, Gulf of Thailand, has no increase of tenants during last month. It was increased at an average of a hundred birds per month for the last 7 months. On the contrary, another friend's birdhouse located at the West side, Andaman sea, has more increment during last month.
So season or wind direction is definitely a factor.

See the video of my current design with open roof type. Birds encounter very strong wind when fly above the open roof. Left side is East, front side is North.



So to improve on the wind factor, to make birds feel safer when approaching the entry hole, I am thinking of two types of renovation.

Type A, just build up a wall, 1.2 meter high on the East side of the open roof, to shield against the North - East wind. For the below video, right side is East, front side is South or just remember that staircase side is West. Sorry for the inconsistent.



Type B, to seal up the open roof, and open two new separated entry holes at North side and South side as suggested By Khun Harry in his blog. But in this case, my big roving room from the original design will go down the drain!
Stair case side is West side.



I am proposing these two revisions to my partner, not sure whether he will agree to either of them or not.

Any comments from the readers are most welcome.
