Alright so my hobby is basically putting up birdboxes throughout the year, and this year I have actually experienced my first pest issue whith house sparrows. We have one pair whith chicks who aren't an issue, but one set has taken a box and is causing conflicts whith my other birds (wrens, swallows, chickadees etc.) I don't want to kill them but I'm going out of town in a few days and I'm not sure if I have time to look after baby birds once I get back (if I do they'll be living in an aviary at adult hood) should I choose to remove them. They'll be hatching a few days after I leave. And before anyone asks, yes I attempted to remove the nest during construction but that just led to them attempt to hijack my violet green swallows nest...any advice?
