Hi I spend a lot of time on sister site TEG. I always loved ducks, I have wanted East Indie ducks for the longest time . I bought a pair sight unseen, they are very hard to find here. I am setting up a run for them, question is where. I have a cement slab, positives nothing can tunnel in, I can hose clean. Not sure ducks feet on cement. Other choice is lawn, positive more natural ,bugs and grass to eat. When lawn starts getting muddy move run to another spot. What is better for ducks cement or grass? Thank you
