What glue and screws/nails should I use to construct a freestanding 12mm thick structural plywood dovecote which will be outside permanently.
A dovecote or dovecot /ˈdʌvkɒt/ (Scots: doocot) is a structure intended to house pigeons or doves. Dovecotes may be free-standing structures in a variety of shapes, or built into the end of a house or barn. They generally contain pigeonholes for the birds to nest. Pigeons and doves were an important food source historically in Western Europe and were kept for their eggs, flesh, and dung.
