I see quite a few boys. An exception may be the one in the pop door, I don't see the shiny hackle feathers there. And the one in the back of the 3rd picture.
Honestly I think this breed is very tricky!! Here's mine~ People say I have 2 Roo's and 1 Female they are 7 weeks old in these pics~ but there are days I wonder?? So I went out and bought 3 more BO's just in case~ watch me end up with 6 Hens! lol Goodluck~ Just give it time, wait and see
