I have a 1 1/2 yr old rooster that has a throat infection. his throat is very swollen and he cannot eat or drink. He was at the vet yesterday and got steroid shot and antibiotics. He has gotten dehydrated and I want to give him sub q fluids but my vet is closed today and no one will sell me the fluid. does anyone know what I can use for this? or how I can make my own?
