Some ducklings are just a bit skittery. However, my experience with ten runners is that some would cuddle, some would hang back. I kept up with singing, sitting near them, moving slowly, staying as low as possible (thanks, dfo) because especially after about two weeks of age, they became TERRIFIED of anything taller than they are. After a week of age, we began giving them just a few peas (thawed frozen). Wow, they love peas! Peas helped us forge some serious bonds. Even the one duck (Elf) who won't eat out of my hand will let me pet her and pick her up. About six of them are happy to be petted. None really loves being picked up. But when I sit with them, about half of them will noodle around me, checking out trouser cuffs and pockets. Neun will actually sit right up against me and doze off. They follow me around and stick pretty close. They call out to me when they hear my voice (makes phone conversations interesting).
