Well I had a doestic mallard a few years back, but sold him because he was too rough on my girls. a few months ago I recieved a duckling from a friend. Seems one of her friends got two eggs from a wild mallard nest and incubated them - only one hatched. Jelley bean is now almost three months old - and she is smaller than my almost two month old swede x runners. So - is she just smalll or is this normal for wild mallard size?
