Bearded Dragon Questions?

Hi Guys! I have a few questions. Im planning on getting a Bearded Dragon soon, and Id get a baby. I want to know what to feed it, and How many a day I should feed it. I know I should do a salad every day, but I wanted to know what else. Also, Whenn its full grown, how many mice should I give it a week? And how many crickets/ roaches? I want a real answer not one like "Hahahaha I like Bearded Dragons." Thanks.
