Aggressive pullet or rooster?

[Cinnamon11]

I have 4, 15 week old pullets. But this morning I came to let the chickens out and my EE spash, Lilly was attacking my other EE! She comes up from behind and grabs onto Nuggets neck! Nugget is freaked out and to scared to hang out with the other pullets. She was top boss too! Is Lilly a rooster or just very aggressive? Should I separate Lilly?

Sounds more like a cockerel but pictures will confirm it.

Should I separate them? She is freaking Nugget out and now Nugget wants me to hold her all day.

He's a cockerel.
She's just not ready for his advances yet. I would separate the cockerel from the pullet until she is ready.
Just the two birds?

Yeah I kinda figured. The weird thing is I have two other pullets but Lilly isn’t trying to mount them or do anything with them! The black and gold one (Tila) even gave him a little peck to say I’m boss which is really weird! I also have two hens but they are all dead scared of them.

He was also biting me this morning!

Here we have plenty of space, out-of-sight places, and multiple feeders and waterers, and leave the cockerels with their flockmates. We also have adult hens and roosters, who help civilize those adolescent boys.
Your cockerel is has those hormones influencing his behavior, and no adults to squelch his ego a bit. I'd leave him with the pullets, depending. More hiding places, more space, and no injuries, all good. Too much harassment, not good. Any bad thoughts in your direction, definitely not good!
He could move on elsewhere, if this is your first flock, and consider having cockerels next year instead.
Solitary confinement is bad for any chicken, not a good option, IMO.

I have a large run for how many chickens I have with lots of trees and other good hiding spots but sadly all 4 were very bonded and it seems Nugget is too scared to hang out with her friends anymore. Lilly is in a smaller pen in the coop still so he is still in the middle of the coop so he can be with his friends without harassing Nugget. Sadly when he starts crowing I will have to rehome him because I can’t have roosters where I live. It’s not my first flock I’ve had many before but thankfully I’ve never had an accidental rooster before. Thank you!
