I have 5 2 week old Pekin/Cagyua X ducklings. They were brooded by their Pekin momma but currently living inside in a spare bathroom. One of them (I call Pingu) is much smaller than the others. I'd estimate 1/3 of their weight. However he is doing fine and not picked on by his siblings. Does anyone know what the future holds for him (it could be a her)? I am inclined to keep him with Mom&Dad when I move the others. Will he grow to normal size? I think he probably just lacks the genes for super fast growth of domestic breeds and is developing at about the same pace as a wild duck. This is a photo of little Pingu next to his big sister Star.
