Hi I've just gone down to feed my khaki campbell pet ducks and one cannot stand up, she has both legs completely stretched out behind her. Her crop feels empty and I've looked down her throat and cannot see anything. Does anyone have any suggestions? I've felt all over for paralysis tick. she's approx one years old and we live in a small country town with no vet available. I have hydrolites in the cupboard I can give her and Triple C broad spectrum ornamental bird antibiotic, can I use this?
