My Pekins are 5 weeks old. Yesterday I brought them inside for a swim in the tub. We are planning on getting a kiddie pool soon. As they were swimming I noticed that Ming Ming kept putting his(I think he could be she though)neck over Daisy's. Once it looked like he tried to mount Daisy. I figure it is more a a domination thing. Also when do they start to quack? I have heard that you pick them up and the female quacks while the male sounds raspy. They both sounded raspy when I picked them up to take them to the tub. Although Ming Ming quiet down and Daisy will not while being held. As I took them back out side they were both much louder but not really a quack either.
