Oh another thing, All my boxes do have nest box plates on half 28mm half 32mm. I think having the metal plates on helps when the birds "test" the hole makes it appear strong. I know alot of boxes get used without plates so don't think its a must but if box appears stronger around the entrance during the "testing" stage I believe it may have some help in it being used. Sorry for the long message above didn't realise it was that long  I can go on with myself when I get started!
