Hi, Josh, we are so glad you are here and thank you for sharing pictures with us!
If all your girls are the same age and laying, just based on the coloring, lacing, and no male-specific feathering that I see, I vote that your Wyandotte is a she. I hope she lays some eggs for you soon! Others on here definitely are more qualified to answer than me, though.
