Ok so everyone or most everyone knows about Shifu lol I like to bombard the pic posts with her. Anyway she is supposedly a Jumbo Pekin/Rouen mix. And I have a couple questions. 1. Do Rouens grow slower than pekins? 2. Do Rouens feathers come in slower? 3. Anyone else with a rouen/pekin mix -- are your ducks as large as a pure bred rouen or pekin? Now size wise at 5 weeks she is just as big as my 9 week old Mallards. Po my pekin was much larger by 5 weeks old and fully feathered. Shifu is about half feathered at 5 weeks. I guess I figues if she was a mix between a jumbo pekin and a rouen I expected her to grow fast like Po did and to end up large. Hmmm I wonder how big she'll end up. Oh and for good measure here is a new pics Taken today, she is 5 weeks and 2 days old.
