I purchased 4 Egyptian goslings at less than a week old. At that time, they all looked identical. Now, at around five weeks old, they have feathered out and three look the same. One looks more like some kind of big ornamental duck than an Egyptian. It's head is even shaped different. So my question is, do the different sexes vary that much that young or do I have something else. Is there an easy way to sex Egyptians?. Color patteren is a little different too. Any help would be great.
