Let’s play everyone’s favorite game… hen or roo!

I have an establish flock of 10 sturdy breed hens from last year (bought 10, all survived and wound up being hens) and wanted to grab some cool breeds this year. Got 2 Sicilian buttercups, one cream legbar and one partridge rock. I was honestly hoping for one rooster to handle the flock…but I think I got “lucky” again with all hens. Any insight on if any are Roos?
