Young chicken is sneezing up a lot of fluid, eyes look off and her chirping is different

ask however many questions you need to, I just really need to know what's wrong with her

She could have a respiratory disease. She looks to have conjunctivitis (pink eye) and possibly a sinus infection. Cannyou see a vet near you? If not, I would get some antibiotics soon and start giving them to her. Also now, she needs to drink plenty of water, and I would keep her separated and offer watery chicken feed throughout the day in a small cup or scoop up to her beak. Tylosin, doxycycline, enrofloxacin, and oxytetracycline are some of the possible antibiotics that you can use to treat her. Here is a link for buying Tylosin:
