Unless you seen something doing this they may of died and parents pulled them out? If put wooden guard make it at least 1 inch thick (this will limit reach and head size of anything reaching in) and slightly bigger than entry hole due to thickness of entry once modified.

I also had 60 pairs Martin colony in okieland. I can tell in okieland Purple martins are hard to get colony started and twice as hard to keep it going.

Thank you so much
