I have never raised any animals aside from dogs and cats, until now! Fell in love with chickens and decided to take the poultry plunge! On Sep 25, i received 5 Barred Plymouth Rocks and 2 White PR's. They are now hopping ready to be outside in their coop area. Being the newbie that i am, i purchased 2 "chicken hutches" from TS, put them together, built a nice large fenced area around them, with heavy netting over the top, chicken wire and steel farm fence on the sides ect. After painting them ever so cute, with "Mary engelbreit" style flowers and chickie tracks, i realized that no one on here recommended the hutches. They are too small, and have no insulation. Now that im pretty much stuck with them, i had to make do. I added an extra layer of plywood, with insulation covered in plastic sheeting in between, and have tried to make them as cozy as possible. Because they are so small, i don't see anyway for them to have a heat lamp in them at all. I planned for 3 chickens to sleep in one and 4 in the other. There is a roosting bar and nesting boxes in each, with lots of straw and pine shavings for bedding. I've gone into such great detail, to ask the question: Is it okay to put them in non heated coops (our weather right now dips down into the low 30's at night) considering how close they will be to each other for body heat? If not, what should i do? Any suggestions for heat would be greatly appreciated!
