The wren in the pot

I grew sage in two pots last summer. They are an attractive plant, but one was killed by winter. The other began putting out some green at just about the same time we discovered a wren had created a nest there. What to do? It seems these wrens will nest anywhere. I left a sack of potting soil out for a couple of days two or three years ago and a wren built a nest there. It was in the way, so I couldn't let that stand and it was early enough that another could be built. Another year, one constructed a nest in a hanging plant on our front deck, so we watched the family develop and then fly away. The nest in the pot is cleverly made and even has a roof. Every time I watered the plant, the wren fled with an extraordinary rapidity; not taking flight, but running into nearby bushes. When she was gone, I looked closer and caught a glimpse of an egg, and I assume there are others. Watering the plant can't be good for the eggs, and I don't like to frighten her. So I've decided the sage plant must die for the wren family.
