And I have the two nest boxes, but they are big for bantams, so I am thinking that 2 can maybe fit in one box....but we will see. I like the way the nest boxes turned out. The upper one has two open sides, with a lip to hold in the hay. The bottom one is much darker, with only one small opening. Now I forget how big they are..... I think just over 12 inches deep and 18 inches wide. The bottom one 10.5 inches tall, and the upper one is taller, maybe 12 inches.
