Chick won’t stop chirping! Help!

Hello! This is me and my husbands first group, we had them from egg to hatching. We have 11 total. Well the last one born on Day 22.5 who is quite small (definitely the runt of the group). She’s had multiple pasty butt situations but handles butt baths well. However, she will not stop chirping.

To give some context…

We check her for pasty butt constantly

Has had olive oil on her bum to help

Moved to her own brooder with one sibling (another one on the small side, second to last born)

Been given a little egg yolk and mush (started feed with water)

She is eating and drinking. Definitely better than when she was with the 10 others

Her heat plate is low and she has room to get out if she gets too warm.

PLEASE HELP. I don’t know what’s wrong or how to help her! :(

Her name is Peep (unironically, named before her loud voice was discovered lol)
