Standards mature slower; at 5-6 weeks of age there may likely be surprises so I do have doubts-but here goes...
Noodle - Wyandotte PULLET
Pikachu - Easter Egger ROOSTER I find EEs harder to sex.
Spanky - Russian Orloff PULLET
Fancy Pants - Light Brahma PULLET
Sheriff - Rhode Island Red ROOSTER Definite
Again, there is room for doubt on some of these.
