it does take some time to get used to site. Hopefully those that can help answer and follow the breed/gender forum will be able to tell you what you have.
You have some nice looking birds and I like all the play things you have in your pen. Good job on that.
I'm seeing pullets. Maaaaybe one or two cockerels if they are very young. (Look for thicker, larger, redder combs- but pullets redden when they are getting ready to lay! Keep an eye out for saddle feathers.)
Mine are about a month old and the males are obvious.
