Outside Temps and Ventilation

[llombardo]

I keep seeing that as long as the coop is dry and draft free fully feathered babies should be ok. I also see that the vent should be open. Wouldn't that vent being open cause a draft? There is also a side window that is lower for what I assume is for warmer weather to get a breeze.

So does the vent stay open or not, when they are babies and it's not exactly warm?

More info. What size coop? Pics? Age of chicks? How many?

For reference, my chicks are brooded in a grow out coop. Ceiling level vents open all the time. During the day, windows or doors are open and they have access to the lower level 8 x 12' run after the age of 2 - 3 weeks. Temps are 20's at night, 40 - 50 during day during first few weeks. By the time they are weaned from MHP at 4 - 5 weeks, the temps vary from low 30's to high of mid 70's.

This is the coop. The window is straight ahead if looking at the coop. The vent is on the left side, closer to roof. There are 4 chicks. They won't be going out for another 3 weeks(when the run is done). They will be 6 or 7 weeks old.

So the vent near the ceiling won't cause a draft?
