I also have a theory. If you've seen the finale of RTTE, then you know what the Bewilderbeast's nest looks like. It's made of ice. This means that unlike other dragon eggs, which need fire to hatch, a bewilderbeast egg needs extreme cold. Valka may have taken the bewilderbeast egg she got to an extremely cold island, and let it stay there with Cloudjumper to watch over it until it hatched. Because, let's face it, there are a LOT of cold islands in and outside the archipelago, like Glacier Island. Valka could just have taken the egg to one of them. That would speed up the hatching process, allowing the Bewilderbeast to grow much more quickly. Also, as you may know, most dragons grow very fast from a small size to a gigantic rate. Take Torch, for example. A few weeks/months away from the Dragon Riders, and he grew abominably large. All dragons are like that. So there's no reason that Bewilderbeasts are any different. I rest my case.
