I need some help to figure out the sex of one of my wyandottes... My husband thinks we have a roo and a pullet, but I'm not too sure. When our silkie was a boy, we knew very quickly. These ones are 17 weeks, and just in the past two weeks have they shown drastic changes in their combs and wattles. I got them from my pet chicken, and I paid to have them sexed, but mistakes happen! Any insights would be helpful!

Muffy is the one on the left (possible roo) and Edith is the one on the right.
