I asked a question about coops a while back and didn't get a response, so I was hoping maybe I could get some help this time around. So here is the general idea, and I would like to know if you have any suggestions. Chickens: We will have about 50 birds out there when the chicks are old enough to go out. There is a second coop being built as well, but we wanted to get one done quickly. Coop in question: Originally an old corn crib. 20x8 ft with a 10+ft roof in front down to 8+ in back. The front has holes in the top already, but the rest is far from draft and predator proof. However, I have a ton of pole barn siding leftover from job sites that I would like to use. I know that condensation is going to be the biggest problem. But I was hoping that the holes in the top would be sufficient enough for air flow. There are also two doors in front, and most likely one will be the human entrance and the other will be made smaller for the chickens. I have done my best to illustrate what my idea is in the picture, but I don't have specific measurements for the windows up top. I just know that everything will be screwed down and covered around the entire bottom to prevent any unnecessary visitors from entering, and the windows on top will be covered in hardware cloth. Here are my biggest concerns: I love the corn crib and do not want to destroy it, therefore I do not want to have to cut any unnecessary holes. So hopefully one day the siding can be removed and it will look the same as it did before. Condensation- not sure if the set up will allow enough air flow to prevent this, but I also know that any time it is warmer inside than it is outside and if humidity is high, there will be condensation on anything, just more able to see it on the metal. Ventilation- is this enough or do I need more? Temps inside- it gets pretty hot during the summer and pretty cold during the winter. I do not plan on insulating the coop. As all the breeds we have are cold hardy. The metal is silver so shouldn't absorb too much sun, so I don't think that there should be too much trouble with overheating. Anything you see off hand that looks off or needs to be changed or if I need to scratch the metal idea all together, I would prefer it be addressed before I get the entire thing built this weekend, if it ever stops raining. I forgot to add the pic the first and second time sorry. This is obviously photoshopped, but this was my idea.
