I have a chick that is suddenly gasping for air. I separated her and tried to give her some sugar water. She's very weak and can't stand or hold her wings. This just started a couple hours ago. What else do I do?! They have had 1 round of save-a-chick electrolytes and probiotics in the water. All other chicks seem okay for now. I just lost a chick this morning because of it's gasping for air! What do I do? What can I do? and what antibiotics do I need to get from the vet?
