I have 3 pekins about 7 weeks old. I am trying to figure out what sex they are. Their quacks are still coming in and seem to peep and quack off and on. I googled and searched here and it seems the bill color could either be gender related or that one had an Aylesbury sometime in its lineage. Can anyone clear this up for me by chance? I have added a picture of Scooter and Fluffy Butt. Scooter has the pink bill. No curly feathers on any yet. My other pekin, Steve, has an orange bill like Fluffy Butt. I'm sorry if I missed the answer in another post. P.S. I got them at Tractor Supply and of course they only sell straight run.
