Boy are they ever! I started out with four and I now have sixteen with seven eggs in the 'bator...the two Poms I bought off a person at a roadside poultry debacle...he was kind of throwing them around by their little heads and necks in an acquariaum thing...I had to take them out of there...I also bought a white chinese gosling that did not make it...the five crested Rouen ducklings he had in with the geese had to come home with me too...they are doing fine...
two of the crested Rouens and some of my Magpies, Runners and Blue Swedes...almost ready to go on the yard...I keep them contained for a time until they can manage with the older ducks and geese and not be so susceptable to hawk attacks...
I think they are right at 4 1/2 weeks...the growth rate on them is just incredible...the Poms might be a week older...and yes, they were little yellow fuzzies when they got here...

don't you just love the Don King effect of the standy up hair on their little round noggins?
