Just a detail question that I haven't been able to find the answer to.
What is the difference between "Draft" and "Ventilation" ?
I have a 6x7' shed we converted to a coop with two 2x2' windows with slates about 3 feet of the ground. I have a man door that I leave open each morning/day and close at night. There are 4 roosts at various heights that they use, but most of them sleep cuddled on the floor (pine bedding). I have a heat lamp to add a little heat (it is 25 degrees today.)
My girls are 13 weeks old and seem to be doing fine. However, we wanted to add a "door" for them to go in and out of as they want to without having the mandoor open. I am afraid that will create a 'draft', so I wanted to find out my options. Any ideas?
