Hello, I live in England and it rains a lot especially this time of year. My duck run is like a muddy bog because they absolutely love digging and putting their heads in the puddles looking for treats. I was thinking of completely redoing my run and possibly lining it with pea gravel. Does anyone have any experience with it and is it safe for ducks feet, also I’m worried they might think it’s a snack. Or should I look into using wood chips? Any help would be appreciated
