HELP WITH BABY CHICK LUMP ON NECK

[Hoglord]

Please help! My baby chick has a hard lump under her beak on her neck! She is 6 days old and since yesterday day has been throwing up clear liquid and keeps twitching her head and opening and closing her beak. Was chirping a lot but is now sleeping more. We thought it was sour crop since her crop seemed a little swollen but now we are feeling a hard lump under her neck. She has been eating and drinking a little. Please help!

Hello, my week old chick has this issue too. Did you find out what it was? Did she make it?
