A few days ago my little chick got sick. He was sneezing and had a stuffed nose. Also, he's breathing very heavily. We separated him from the rest of the chicks of course. We gave him some VetRx yesterday and now he doesn't really seem congested, but he's breathing very heavily!! He's not really sneezing that much either. He doesn't really want to eat. We're giving him some pedialyte but I want to know if there's anything else I can do! Somebody please help!!
