4 Swedish Flower Hens--guess the gender?

[Margiechickmom]

I have 4 adorable Swedish Flower Hens (that I hope are all hens!) that I hatched on March 20th, making them 3 1/2 weeks old. I don't see noticeable differences but I'm not sure in this breed at what age noticeable differences show up between pullets and roos. Anyone with knowledge of the breed care to guess? It's killing me not knowing because I can't keep roos.

I have always wanted Swedish flowering hens! Where did you get yours?
