I built my coop this summer and used BYC whenever I had questions. I officially joined BYC just a few days ago thinking it would be good to connect with other back yard chicken enthusiasts. My coop is probably overbuilt because I wanted it to be able to be repurposed in case we ever decide to get out of the chicken business or if we were to move. It would make a great shed or dog kennel someday. It is heavily insulated on all sides including the floor and roof, well ventilated and wired. I got much of the material for free or low cost off Craig's List, It did however, take me much longer to build than I had planned for. It was late summer before we got our hens... eight golden sex links that were just starting to lay. They have been fantastic egg layers ever since. Since then, we have added seven Rhode Island Reds, one Buff Orpington, one Black Australorp and one Barred Rock to our flock. I have run into a few problems and was able to easily overcome them thanks in part to BYC! We are currently getting 16-17 eggs daily from our 18 hens. I have two lights in the coop providing 14 hours of light daily. I have a heated water container but no space heater. This winter the coop has remained about 30 degrees warmer than the outside air temp and has not dropped lower than 20 degrees even when temps outside have dropped to 20 below. I raised chickens once before, about 35 years ago in Florida. There is much I have forgotten, plus now I have Minnesota climate issues to deal with. So any helpful advice would be much appreciated! Since this is a new member Intro, I thought I would include five facts about me... 1) I am a potter (wheel thrown, functional), hence the name "MnMudSlinger". 2) I teach art to "At Risk Students", K-12 3) I am Minnesota Born & Raised. 4) I am a Veteran of the Navy & Army 5) I love the outdoors! Have a great day everybody!
