Our polish girls are about 10 weeks old now. They're all supposed to be girls but the silver laced has me wondering. She is very people friendly, very bold/adventurous, and definitely the alpha of the pack. We introduced 3 new chicks, all of which were bigger than her today and she was terrorizing them all. She does seem to have more spikey tail feathers than the other two although she doesn't hold it high like you would expect if she were a he. Anyone want to chime in and place a bet?
