We have 5-day-old ducklings and I've been reading up on old threads to find out what kind of treats to give them, and spinach and other greens seemed to be a big favorite. I'm wondering if it's OK to give them things like egg, cheese, and bread -- our chicks always loved those. Also, is there a way to stroke them that they appreciate? They come to me like they want to be picked up, but they're so darn wiggly I can't tell if they like being touched, and they have a nasty habit of wanting to "perch" on my arm where they hunker down and look quite comfortable until they tumble off (I sit close to the floor!).
