Hoping that they are doing well this morning! If it makes you feel any better, I found out far too late that foam insulation is like crack to ducks (and chickens apparently, from what I’ve heard). I had some exposed that I did not know about that my ducks found and went to town on before I stopped them and covered that area up. They had no ill effects. Another time, some styrofoam (from I don’t know where) blew into their area and got devoured immediately. They pooped out little white styrofoam balls for a day, but were once again fine. Hopefully, your ducks will be ok! Definitely keep us updated!
