My chicken is very lethargic, and shaking her head a lot

[Chimichangas]

This chicken is being bullied by the older ones. Which has caused some problems with her eating. She is extremely skinny and lethargic, but apart from that she won’t stop shaking her head. What could this mean? She also doesn’t lay down no matter what, she has been sleeping standing up. I have separated her from the rest and made sure she has food and water.
The way she is standing on the picture is the way she has been standing for a day now.

Head shaking can be caused by a foreign object stuck in her throat or beak. So take a close look.

Ear infection is another cause, inspect both ears to see if there is gunk or smell of infection.

Inspect her closely allover for poultry mites and lice. Mites can leave a bird anaemic and dizzy in no time.

Being pecked often on the head by the other chickens can cause head aches, dizziness, nausea and other neurological syptoms.

How old is she?
Is she the only younger one?
When and how did you introduce her to your existing flock?
When did she last lay an egg?
When did you last deworm?
WWhat about her vision, are both eyes healthy and well functioning?

You can give her some scrambled or hard boiled eggs with fine oats and millet to entice her to eat and restore energy. Some fresh beef liver can also help.

She is a month and a half old, there are 13 more chicks her age, but I do have 3, 1 yr old Rhode Island reds which might contribute to the issue. Her vision is perfectly fine and I checked her ears and it’s ok. I haven’t tried dewormin her yet as she is very young. How could I do that? I will try out the oats and eggs to see if that helps her too. Thanks!

I would keep the Rhode Island Reds separate from the young ones as they obviously are too aggressive and can easily kill chicks that are too young to defend themselves.

How much space do they all have inside and outside the coop?

Can the chicks get away from the attacking adults and hide out of sight?

How many well spaced feeders and water dispensers do they have?

I showed her and asked a friend what it might be and they said that it was caused by a hen pecking her too hard. Is there anything I can do to help her feel better? She also didn’t want to eat the oats.

Yes, the adult RIR can be vicious and should not have access to the chicks at all.
By bullying them constantly they keep the chicks away from food and water, so literally starve them to death in addition to severely injure them by pecking if you allow this to go on.

Did you try the mashed boiled eggs or scrambled eggs?

Add poultry vitamins containing B complex and E to her water to help with nerve repair.
Does she drink on her own?

You might need to tube feed her if she is not able to drink or eat on her own.

Here is how to
