Your friends are not right. Things don't just scale up and act the same if you make them bigger. Galileo discussed this issue at length in his Dialogue on Two New Sciences. He pointed out that if you made an organism ten times bigger (in lengths) it would weigh 1000 times as much. The cross-sectional area of the legs, however, would only increase by a factor of 100. They'd break under the weight. A similar argument would apply to the wings of the giant bird.
