My hen is suddenly acting aggressive towards me when she never did before

[Cardia]

Hello! I’ve owned several chickens before but this is my first time owning a Silkie chicken. I’ve had her for about 5 months now and she’s always been very calm and tranquil but very recently she’s started behaving really aggressive towards me, she won’t leave me out of her site, following me everywhere and trying to peck me. I’ve also noticed sometimes she will start fights with my rooster. Now I am wondering if she’s even hen or a rooster and why she is suddenly acting so aggressive towards me. This is my Silkie in the photos.

Cockerel 100%.

Ohh really? I’m curious how can you tell? Also if it’s a cockerel then why doesn’t it crow like my other rooster?

Yes, he's a cockerel that has matured and is trying to protect his girls/territory. He has a giant comb and wattles that are much larger than a pullet's would be. Also, the streamy long feathers coming from his head and tail area give him away as a cockerel. He probably doesn't crow because he's subordinate to the other rooster, but if he's starting fights and getting aggressive then he might be trying to take over the top spot.

I've never had silkies but he has a big thick comb so yes a cockerel.

Sometimes if there is an older or more dominate roo nearby a young cockerel will not crow very early.

I'm not gonna lie that second picture looks really ominous, like something is about to go down...
That needs to be a picture for the Caption Contest.

The large red comb, & wattles. He also has streamers on the back of his crest, pointy saddles, & sickle feathers.

She is definitely a he. He is supper handsome.

Hi accidentally stepped on one of my hens. Now she pecks at the shoes that hurt her. Can’t blame her for that.
