Hi, Betsy: I suspect wrens would go after HOSP eggs as well as any other bird nesting in their territories, but that is hypothetical. I have no actual experience with them doing so as HOSP's usually try nesting in boxes that are not around HOWR habitat. BTW, congratulations on your wren-less EABL trail. Oh that we had it so good.
