My chick has had ruffled feathers for the past 4-7 days. She is smaller than all the other chicks and not really growing, so I thought she was the runt. She almost always has her head tucked or in her wing, tail down, and down in a crouch. She does not have a swollen face or anything, and does not have runny eyes or nose. Her feet are usually cold. She doesn't move much. She just sits there and when she does move its slow, and her neck is still tucked. She does make a weird noise when she breathes but it's not loud. I don't know the last time She has used the restroom. She doesn't eat or drink much either. She doesn't really interact with the other chicks much, but she will chirp at them sometimes. She also make a "twur" sound sometimes. All the other chick act fine so I think it's just her. I don't think whatever she has is contagious. If she has anything, it might just be the way she is idk? I think have covered everything. Someone please help, I want to be able to help her if she needs it, but I don't have enough money to go to the vet. She also breathes out her mouth sometimes.
