OK, so I think I know the answer to this one but just want to make sure before I buy nesting boxes. I have 4 bantams but 10 other larger chickens and to conserve $$$ I thought it would just be more practical to go with a set of the large 14" boxes so that everyone could fit. This shouldn't be aproblem, right? I would think the little ones would use them too. What do you think or have experienced?
