Considering my little pullets may start laying in the next month - couple months? - I would like to have nest boxes at least ready for them. I don't have much room in the coop so the stacking nest boxes should work fine. I'm wondering, though, how many I will need. I have 11 pullets, all about the size of a pigeon or morning dove. If I have one bin that's about standard size (about 12"?), that should fit at least a couple birds and work as a communal nest, right? Would it be better to have two boxes, though? If they are stacked on top of each other, will I have to secure them to the wall even though these aren't large fowl? I don't want them to tip over... Will bantams even use a nesting box that large? Also, because of the size of the coop and the position of the roost, If I have two nest boxes stacked, I would probably have to have them facing the roost and they may end up being almost level with it. Will they still use them? I appreciate any help/advice that anyone has.
