sexing Silver laced Polish, 3 1/2 months old.pic heavy

Hello again Polish experts.
I just found out that my Polish's hatch-brother has started crowing. Neither of mine are crowing. He also had big bright red wattles at 2 1/2 months old. My two currently have a very slight pink/dark pink around the beak. But definitely not red.
By the way, their hatch day is May 1, so they are now 3 months and 3 weeks old.
Do I still have a chance that they are both girls?
Crossing my fingers...

Confirmed, Perdita is a girl and Pongo is a boy. The saddle feathers are even more pointy, he is getting bigger, taller and his neck and head feathers are more boy.
Also, the wattles are coming in on Perdita now, and Pongo is getting very red about the face just this week.
