We get hot and cold weather in Illinois. Our Wyandottes and Eggers to arriving soon ( April) and I am handy, but not certain if I am able to build a coop. I was looking at some of them sold online, sites advertised on BYC and ebay, and noticed that none of them are insulated. Here are my questions: 1) Since I have a cold hardy bird, do I need a insulated coop? We do get into the negative degrees here. 2) Can I buy one and insulate it myself? Has anyone done this? 3) Are the ones you can purchase online strong enough to withstand predators? I am not certain of the strength of the pens. 4) I have an old dog pen I was going to use with a chain linked fence. I was going to wire the top with some 2" wire that someone gave me for free. Is the 2 inch on top okay to use to protect my feathered friends from cats, birds, coons etc? Do I need the 1 inch on top? Can I use the 2" as a bib for diggers? I'm thinking I need to wire around the linked fence too. Thank you all for your time and answers! The more I search, the more I learn! I love this site..and yes it is addictive!!!!
