I ordered some ducks (and chicks) from Ideal, and I'm not entirely sure that they sent me the right ones. I ordered crested fawn and white runners, black runners and a few pekins. Two babies (one black, one yellow) died within a few hours of arriving. The rest are growing like crazy, but I see no sign of any crests. My crested chicks' crests were apparent right away, is it different with ducks? Or do I maybe just have non-crested runners? I'm not even entirely sure the remaining yellow ducks are runners at all. The only obvious difference between what I think are the fawn and white runners and the pekins is size. Do people usually have good luck getting what they ordered?
