Nothing you really can do, besides make sure it has water at all times and try offering food every so often. As I've pointed out in several other Avic-related threads, they'll sometimes take a while to settle in. It could be weeks or months before you see a significant amount of webbing. As for destroying some of it, it's natural to feel a tad guilty, but it really doesn't bother them that much and most of the time they'll re-web very quickly. This is just part of keeping Avics.
