Return of the Hawk

​Earlier today, during distance learning, I heard quacking coming from the yard.  I saw a hawk, and I went out and chased it away.  This was the third time this had happened so far.  And the hawk had been stalking my birds for a while.  When I looked closely at one of my ducks, I noticed that it had a small scratch on it.  I put antibacterial cream on it, and locked the ducks in the pen.  This hawk has really been a problem, and I think it's the same one each time.  I'm not sure how I will deal with this hawk.  If you have any advice, please let me know! -Henry
