Oh my, that photo with the raccoon is terrifying. I'm so glad you brought them in. It sounds like you really love your ducks. Good job keeping them safe.
I have also seen racoons during the day, you may want to only give your ducks supervised outside time. Our neighbors had a duck who was killed by racoons. The racoons pulled his head through the bars of his coop.

I'm sorry, but I wanted you to know what can happen so you can keep it from happening to your ducks.
Have you read Enslaved by Ducks? It's a great book. I believe the author trapped and relocated 8 or 9 racoons before giving up. My point is, even if you relocate the raccoons you see more will come, eventually. You will still need to predator proof your duck enclosure.
