This is a fascinating question. I doubt they'd find you on their own, unless their territory spans that far. If you're moving out of their territory, it would be awkward for them to barge in on another crow's territory to interact with you (bad crow etiquette to invade neighbor crow's area). You could do two things: 1. bring a pocket full of peanuts, go to your old house, and find them. Leave a trail of peanuts from your old house to your new while the crows are watching. If you did this a few times, your crows would learn your new place, but as I said, I'm not sure if they will follow or visit you there since it's probably not in their territory. The other option is simply to make new crow friends with the crows that live in your new neighborhood. Please let me know what you decide to do!
