Hi GBH
I always use protectors. It is easier to ensure the correct size is used ie 25mm / 28mm / 32mm. Two of the boxes I put up in the woods have been gnawed at around the plate, possibly by a squirrel trying to get at the chicks. So the plate saved them.
I always leave them natural. Not sure if it makes a difference or not. There was a study done in the 1960's that I saw in an old book called "Bird Nest Boxing" by Norman E Hicking. If I still have it I will dig it out and post the relevant pages on this thread.
