I have 8 breeds and I am building nest boxes and I have been given different dimensions depending on if the chickens are "standard" or "heavy". SO...Since I am new at this, and at the risk at sounding stupid...I wanted to ask all of you more experienced people out there what I have and also if at some time in the future I were to try another breed that might be a "heavy" breed, would it be a good or bad idea for me to build nest boxes that would accommodate the larger breed from the start even though I might only have "standard" sized breeds now? I know I don't want 2 hens trying to use one box at the same time, but I also wouldn't want to have to build another whole set of boxes if I were to change breeds and it wouldn't harm the "standard" breeds to have a slightly larger size box now. I am talking about the difference between 12X14X12 to 14X14X12 (which was recommended in the Storey's Guide to Raising Chickens book). The difference being the width. Of course with the difference in the width, you can no longer get 8 boxes out of a standard piece of 8' lumber. With all of that said...I have the following: Araucanas Australorps Brahmas Buttercups Delawares Dominiques Orpingtons Wyandottes Unfortunately the "Storey" book called all of these breeds "large" (I assume as opposed to Bantum) but didn't specify if they were considered "heavy or "standard". As always, thank you in advance for your help.
