So I have been waiting impatiently for my girls to start brooding, I guess the first nest boxes I built were too small. I upgraded them last weekend. The boxes are 2x2 feet and the roof is 26"x36" on each. I moved all their eggs to the new boxes last Sunday. All the nests now look like this, so I am hoping for lots of poults soon. I can't confirm 100% yet but I do believe a hen actually spent the night in a box last night. If she is still sitting when I get home from work then I will have my first broody!
