Hi, everybody! I've been wanting to have chickens for a long time. Finally, last week, my husband gave me this coop for my birthday!!!! I am so happy and excited to embark on my chicken adventure! I've never done this before and I have a myriad of questions. Here's a pic of my coop: The size is 120.5" X 41" X 48". We assembled it on our deck, but it's going in our big back yard. I ordered an electric fence from Premier since we have lots of raccoons and foxes around here. My (first) questions are: 1- How many birds can I house here? Coop has 3 slots inside the nesting box. They will have additional room to range once I get my electric netting (should be here next week). I'd like to have 3/4 birds, but I don't want to crowd them. 2- Do I need to cover the top window during the winter or do they need it for ventilation? I live in Raleigh, NC. Winters can get cold but they're fairly mild. It might get to the teens occasionally but that's about it. 3- Any ideas on how to build a door for my coop? Thanks a lot in advance!!
