Thanks for the reply!
These pekins quack when they are hungry and I think they are asking for food. Also like yours they'd like to give greeting to me when I am around.
But they have the tails which I read are kind of male characteristic, is that this looking of tails?
They are around 4 months old. But I have no idea they are boys or girls. They are all look same and very loud. I am afraid someday my neighbors will complain about the noise!
Can someone tell me the sex of them? Thanks a lot!
