Hi, We are new to raising chickens and we want to know how to have a nice safe environment for the chickens for winter. We have about 5 dog kennels that we would like to convert into chicken coops. They are on concrete patio block flooring. Half of each kennel already has a roof. What kind of bedding would be best to use on this type flooring? Money is tight, so please advise the very best and cheapest way we can convert these kennels to coops. We live in northeast TN. We need to get started on this project very soon. Even though it has been around 97 here the last few days, winter will be here before we know it. We got lots and lots of snow last year. We can have a fenced in area for our dog to patrol the chickens to keep unwanted critters out. He is already doing this in the kennels we have them in that are on the ground now. He does a great job - has shown no sign of trying to harm the chickens As newbies there are so many questions. I am so thankful for all the information available here. If you have experience, you know what is best! Please share your opinions. Thank you so very much.
