Ok, so I know I have asked this question on other posts, but still have not gotten a response...I have my little "coop" you could call it that goes inside of my run..if that makes sense. I live in fl so I didnt feel the need to build a big house connected to my run, so I am using a piece of a desk that I found, and it has about a 2 inch hole on top and then a 8 inch X 5 ince chunk out of it on the front. I would like to know how many holes to put on the sides for good ventilation. I dont not want to cook my chickens in there in the summer, but want them to be warm in the winter. So, how many holes and where???
