New Chick Owner Pls Help! Sick Chicks!

[ishbish06]

Hello, a few weeks ago I picked up some baby chicks from tractor supply. I noticed a few of them have really smelly and liquidy poop. They have no other symptoms except a little sneezing. I don't know if they are sick or if it's normal? Please help me! Thank you!
