We live in a townhouse and I noticed that two crows were building a nest in the tree around 8 feet from our balcony. I started feeding them dog kibble during their whole nesting process. One of the young ones has been able to land around 4 feet from me to ask for kibble. They now have 4 juvenile crows that they've taught to wait outside my balcony as well. We have an easy power hookup, no issues with squirrels, and a captive audience.
I'd love to see if someone has a box to pass on as I'm terrible at being able to put one of these together. Thank you!!!
