Newbie here I got 7 pekins a week ago. I think they are about 3 weeks old now. They have nearly doubled size in only 1 week. They are a handful, but I just love them! I wanted Khaki Campbells due to the egg production, but I happened upon these Pekins for only $1/each at TSC. I still want Khaki Campbells, but I want to make sure both will cohabilitate in harmony. Can pretty much all breeds of waterfowl be together? Thanks!
