Is there a certain weight for ducks? I worry that Lucky is getting too big. He's a little over 6 mo. old. but he is a big boy. Bigger than his parents. he free ranges but not in a huge area its a decent amount of space though. Lucky is Rouen/Golden Cascade but i think mostly Rouen(favores Rouens most) ~ I keep thinking that his body is getting closer to the ground. lol Thanks, ~Julie~
