Im at a loss, my sons baby chick about a month and a half old has a runny nose the past month. She gave it to my older girls and roster and a silkie chick that we bought at the same time. I put everyone on antibiotic's in the water and also have been giving the baby medicated food. I lost the silkie from the URI but the other chick seems fine except her consistent runny nose and sneezing. She's growing beautiful and even wants out with the older girls now witch has made a complete recovery and I've taken them off the meds after two weeks. Idk what else to do for her. It just won't go away. Please help !!!!'
