It very well can be a blue wyandotte-and at 8 weeks, it could be a boy. If you search about blue dottes, you will notice many DO NOT have yellow legs like they should. This color has been messed with so much(by adding in orpingtons and other breeds), that many do bot carry all the qualities that wyandottes are known for. We raise blue dottes and very few have yellow legs, like they should-and they came from one of the countries top breeders. Give it a little more time and see how it grows out.
