I need to make the nest boxes for my eleven 14 week old pullets. They will be built onto the coop and we will access the eggs outside. My question is this: The area I have is 36.5" high and 32" wide. So, can I have just 2 nest boxes side by side that are each about 16" wide or a 2 x 2 nest box area that has 4 nests, 2 below and 2 above. Also, should they all be 16" wide to use up the 32" I have in that area, or should one nest be 12" and the other 20" or some other dimensions? And should I use the entire height and make the nest boxes 18" high or is that too high and won't be cozy enough for the chickens to feel safe and private. Last question: What is the best depth for nest boxes. I have LF like BO, BR, EE, etc. Thanks!
