[Game of Thrones] How many sheep would one of Dany's dragons need to consume in a week in order to maintain optimal body weight and growth rate?

The largest dragon in the show is shown in season 4 as having a wing span of about 40 feet, which puts it on the same scale as the largest pterosaurs. They had a body mass of about 200kg fully grown so if we assume the dragon has the calorie requirements of a 200kg crocodile then just a couple of sheep a year would be sufficient. However flying is much more taxing and it's likely that dragons, like pterosaurs, are warm blooded like mammals. Which would give it the nutritional requirements comparable to a large male tiger and they need about 10 pounds of meat per day, so the dragon is probably snacking on a sheep about once every 5 days or about 3 farmer's children a week.
