Thank you. If this stands true, then we have at least 4 out of 5 that are female!!!! That would be awesome. They are all about 10 weeks old if TS is right about their age when we got them. We also have 2 Pekin the same age that I am pretty sure 1 is female and the other is male.

Just waiting on our other 2 Pekin to get a little older now to see what they might be.
