these are my 2 sg dorkings from shipped eggs, cockerel (left) and pullet (right)
I only have bantams and EE's to compare with but i'd say they're feathering out as fast as the rest. now reaching 'market' size, I think they take a bit longer, but not horribly so.  My understanding is that "Heritage" breeds aren't supposed to be fast. quality takes time...
reminds me of a sign over hubby's toolbox (ASE Master Tech) says "Good, Cheap, Fast. Pick any 2."  you can have good and cheap but won't be fast, you can have good and fast, won't be cheap, or you can have cheap and fast, but won't be good. this could apply to almost anything in life...  
but for poultry IMO, good = meat quality, cheap = good growth on little food, and fast = time to market size. I think the dorking would fall under the good, cheap category. since letting my dorkings free range, my feed consumption hasn't increased noticeably from what it was before I got them.  
now those EE chicks are going to eat me penniless! every time i turn around the dish is empty.
