yeah I know my pics leave a lot to be desired, LOL cell phone camera+trying to take pics immediately following treat time= really bad pictures HA.First three, lighting is not too good, too much shadow, but I see a darkening of some feathers that suggest male.
Your last set of pics, I only see one, the last one, that looks like it could be female. The lighter one's comb looks male although the pic is a bit blurry. The one with the tail to the camera, I think is male. Looks like some curving sickle feathers starting?
one question though, I thought the sickle feathers were the longest ones that were over the top not from the sides? I guess I need to go download that diagram and study it some more.
On top of thinking I have 4 or 5 of these that are going to wind up being roosters, I'm pretty sure one of the tractor supply white leghorn "pullets" is a rooster too. So I may be rehoming 4 roosters instead of just a couple........
