I am getting 4 Red Stars and I will be using a 10x10x6 dog kennel for there pin. What is the minimum requirements for there shelter and laying box, could I use a dog house with a laying box built next to it up off the ground, would this be enough protection from the cold? I live in north MS and the average low is around 25 degrees. Trying to get by as cheap as I can. I am up for suggestions.
