I live in VT and it gets quite cold....I really wanted my nest boxes on the outside to keep as much floor space as possible. But now I am starting to second guess myself due to the harsh winters. My coop is 8' x 8' and I am getting 5 hens. I would love to be able to get more in the future. How many nesting boxes could I do on the inside and still have room for more hens? How many boxes do you think I would need for say....8 hens? I was going to do 3 for the 5 first hens I get. That should be good for 8 hens right? I don't know, I find my head is spinning!!!!
