In our large common indoor pen, we built an access panel to accommodate access to future nesting boxes and we finally got around to building the nesting boxes this winter.
For those of you who saw our post about the turkey nesting boxes and noted the 2×4 roost, this one is considerably smaller. That is due to the fact that chicken hens way a lot less and also have smaller feet, allowing the more size appropriate roost.
The external access is great, and would make egg collecting chores easier, except we added other nesting boxes in the main pen for breed isolation during the spring egg season. Once we mix the hens again, this will be more helpful!
