We just built our nest box for our little coop and for 8-10 maybe 12 chickens (which is what we're hoping for) and we made 3 nest boxes. Is this enough for as many as 12 hens? The dimensions for each box are 10 1/2" deep X 12" high X 14" wide. I hope that's enough room. I know most people make them 12"X12"X12". Here's a picture of it.
