If I had the cash, I would cover the whole pen with metal half inch hardware cloth. As it is, a neighbor blessed me by telling me how years ago, another neighbor had lost a duck to a fox without even realizing it. It was broad daylight in the afternoon, and a fox nabbed a duck walking in the backyard while the duck owner was doing something out on the back deck with her back turned. She never saw it happen, never heard anything. The neighbor who told me the story was also out on his deck, and saw what happened.
That is why the top of the day pen is covered with coated woven wire, 2"x3". And I know it is not a guarantee.
A friend recently lost her flock to a raccoon that climbed up the chain link, ripped through the plastic "hardware cloth" then reached through the three inch ventilation opening at the top of the door to the dogloo.
Twice last year I heard raccoons yelp from contacting the electric fence around the duck house.
