The Witch and Luck

The witch has flown over my coop like every other night for the past two seasons and at first I was really excited, now I’m just getting tired of it/confused, am I doing something wrong 😭, I remember when I looked it up once it first started happening, someone mentioned it may be tied with luck/may be rare, I’d also like to point out the fact that I’ve found like 3-5 owl statues on my farm in the past year. What is going on
