<human>: Can you condense the text into a few key points?

This is probably not the best sub to ask in, but I wasn't sure where else...

A juvenile crow landed or fell in my yard the other day, and my dog got to it before I realized what it was.  It was injured with probably at least a broken leg, but nothing obviously major.  I set it in a tree overnight, and in the morning it was on the ground again.  When I went out to see about it, around 50 crows gathered in the trees above me, making tons of noise, occasional swooping, and some threatening beak-stabbing.  I went back inside and left the juvenile alone, hoping the murder would somehow deal with it.  Late in the evening, the juvenile was still there, obviously very weak and tired.  With a few crows still left in the trees above me, I did my best to discreetly and humanely kill it and get rid of the body.

Now there's at least 3 crows that haven't left my yard.  I went out of town for 4 days and came back, and today was yelled at, threatened with pecking, and followed to the bus stop.

How can I get these crows to leave me alone?
<bot>: I killed a juvenile crow and 4 days later am being threatened by at least 3 adults, how do I make them stop?
