my little Smith is now 28 days old, i got the little fella as a gift when he was only 3 days old. Lately, even as a small ball of yellow poof he has been very agressive towards me? i dont understand why but what was once a nibble here and there had become very rough pinching and harsh pulling of any part of my skin he can reach. i hold him and pet him for many hours out of a day and he even left me a bruise on my cheeck where he managed to latch on and not let go.. he has tried to put my whole pinky in his mouth too! i belive he is a White Chinese Goose, and a gander too, and i fear as an adult he will be too agressive.. how can i stop this now while he is a gosling? any tips or advice, hes my special little guy but he wont even let me grab him now without nipping at me.
