Ok, I went to my local feed store and found a 20 inch red rubber catheter with a rounded tip. As for the food, I couldn't find any game bird crumble, but I did find a regular duck food crumple. I am assuming this will be ok? Should I dissolve it in water and feed her with that?
The duck crumbles will work. Do you have a picture of the tubing?
You'll want to start off by hydrating her first before you actually tube-feed her. Could you weigh her on a scale, and give us an approximate weight?
