Is my coop too drafty? Ideas on how to fix it?

I'm a super-duper brand new chicken owner and long-time lurker/learner who's really enjoying her chicks!  I need help/feedback on our coop and it's ventilation...

 

We up-cycled a playhouse that my amazing father-in-law built years ago for my children.  It's predator-proofed at this point and I want to move our chicks into it soon, but I'm worried that it'll be too drafty since it has (mesh covered) windows on 3 sides and wide mesh covered doors on the South side.

 

South Side:

(I plan on trying the DLM so that is a piece of plywood for holding in the pine shavings)

 

We also up-cycled a piece of an extra pool cover that came with our house as a roof wrap and as a wind and rain curtain (I plan on weighing the bottom to reduce flapping in high winds):

 

 

West Side:

 

North Side:

(This is where I'm about to build the run and cut the chicken door)

 

East side:

(This is where external nesting boxes will be installed well before these tiny chicks need them :) )

 

I'm in Dallas, TX so it gets HOT in the summer...that's why I decided to make the big clean-out doors out of mesh.  BUT the roosts will be at the height of all those cute round windows!  Do I need to cover the windows on 3 sides and let the doors bring in air?  Or cover 2 sides and always use the curtain at night to reduce and drafts??

 

HELP!

 

Thank you!!

PS In case it matters, I have a mixed flock of Marans, BLR Wyandottes, Ameraucanas, and Welsummers.

Thank you for the response, dreamcatcherarabians!

 

If the chicks aren't fully feathered when I move them out, I plan to put their whole brooder in the coop with heat lamp, draft shield, food and water.  

 

But I am still worried that my coop might be too drafty for full grown chickens if they are roosting at the level of the windows and air could conceivably come at them from all sides (not that it's very windy here, but in a rain storm).

Thanks, flgardengirl. More ventilation?? I hadn't considered the garage/house brick wall giving off heat, but that's something I'll keep in mind. The roof tarp is black, too, so I'll watch the temp. That yard gets a lot is shade when the trees have leaves (they're leafing out right now).

The circular windows are about 11" diameter each, the mesh doors are ~4' wide and 3' tall, there will be a chicken door on the North side and the walls are ~6' long. That is about 20 square feet of ventilation without counting the area between the top of the walls and the roof. I'm not trying to argue, but I'm honestly confused. I thought, if anything, I maybe had too much air.

Please advise.

Thank you!

Thanks, Jack!  I have the heat lamp secured in multiple ways to avoid problems like that!  

 

Also, the tarp is only for when we have heavy, blowing rains and I was going to use it to try to keep the litter from getting soaked.  I plan to let the litter build up (~DLM) so I was thinking that it getting soaked would be bad.

 

Thank you all for reassuring me that I don't have too much draft! :)
