Calling all Tropical and Sub-tropical BYCers!
What do you all recommend for ventilation in VERY humid, hot areas? I live in South Florida (hardiness zone 10b!). During the summer its typically in the 90's or high 80's all day, with very high humidity. Night isnt much better. It almost never even gets to freezing temps at night during winter, so cold is not at all an issue. To make it worse, the only location we can build the coop is in an area already tucked between other walls/buildings.
Looking at the attached pic, the coop is the red box on the left side, and the run is the black boxed area to the right of the coop. Its all small because we're only going to have about 4 chickens.
The southern wall (top in the picture) is the only wall facing direct breezy air, although there are some bushy plants in the way. The west (right side on pic) wall is next best. I was thinking about making at least the top half (or more) of those two walls entirely of screen. I could make the whole wall of screen (except for support beams), but that seems like it would give predators more of a chance of breaking in? Raccoons, possums, snakes, rats, giant iguanas, etc. I'm not sure how crafty these predators can be - should I be concerned, or just secure the screen tightly and move on?
The roost is the grey box (poop board) with yellow line though it (perch itself) in the upper right side of the coop. It's a little over 3ft. If I do the above plan, it should get a nice diagonal breeze by being at the same level as the open screen areas. I figured in my case, it was best to put the roost in the breeziest area.
I'm also thinking about installing some kind of fan at the top of the southern (top) wall to increase ventilation on those stagnant humid days/nights.
There would also be some kind of ventilation on the northern (bottom) wall/door, but I since most of that wall will be door, I'm not sure what I'll do for it yet.
Does this seem like it will be enough? Or am I crazy to put chickens in this corner of the land? (It seems to be the only part of the land far enough away from neighbors to follow the city ordinances, otherwise I'd pick a more open space).
Lastly, I was planning on getting Silkies. I read on the breed page that they developed in southeast asia, which has a similar climate to south florida, so perhaps they deal with heat better than some breeds. However, looking at their feathers, I find it hard to imagine...they seem so insulated. Which is it?
