Just as the title states Id like to know when will my ducks reach full size. I have 3 hatchery ducks from TSC 1 Silver Appleyard Drake(might be mixed breed) 1 Blue Swedish Duck and 1 Blue Fawn Rouen. In all my research I have gathered that these 3 breeds do night fly, or not very well. But My 3 fly rather well and go out on flying adventures daily. They are 5 months old. Is their smaller size due to hatchery stock or maybe they haven't fully grown yet?
