You can observe these behaviours in the wild, and especially among corvids alike. Sure it’s less convenient than using animals in your own enclosure, and perhaps less alluding as they’re not “your” animals. But I reckon for anyone, besides yourself and your friend, involved it would be beneficial if you’d conduct experiments like these through observation of wild behaviour instead. Also have you looked at the literature? Surely these experiments have been conducted several times already by many students in all kinds of flavours.
