How do you feed 6 fawns at the same time.?

Fawns are not very patient when it comes to getting their food. I came up with a way to feed six of them at the same time. Are used a drink carton and put a piece of bungee cord across where the bottles will go. To hold me in better. Then I used a long bungee cord around my neck so that I could adjust it depending on the size of the babies. It worked really good until I had about nine or 10 baby fawns at the same time. I miss rehabbing the babies. It was the best non-paying job ever.
