We have enjoyed all the duck eggs we get from our small friendly flock ( 7females and 5 males). They are various breeds but one small brown duck looks just like the wild Florida Mottled Duck and perhaps she is. (She can fly)

She lays small green eggs and I have noticed an unpleasant aroma from her eggs. Does anyone else know if domestic eggs would be milder and the wild ducks maybe gamey? They get fed Laying crumbles Morning and night but all day forage in the garden and ponds.
