Default House Wrens as Chickadee Predator?

I had a nesting pair of chickadees that had been feeding their chicks for the past week or more. Today, when I went back to that area for another purpose, I saw a house wren fly out of the nesting box. When I looked inside, all three of the chicks had been killed. They were well developed, and well on their way to soon fledging.

I found this upsetting, as I was so pleased to have my favorite species of bird nesting here. I had been watching the parents search the trees and shrubs for insects throughout each day.

The house wrens have an active nest going closer to the house. Are they known to kill the offspring of other species??
