Welcome to the forum! I started out here as well... 10 years and 12 snakes later, I'd have to say I'm hooked lol.
If the hides are too large, you can wad up paper inside them and that will help her feel more secure.
Feel free to check out all the forums and ask as many questions as you like. I'd recommend checking out all the "stickies" at the tops of the different sub forums and also use the advanced search to see if any topics you are interested in have been discussed in the past. This forum has been around a long time so there is a wealth of knowledge here to help you grow in the hobby.
Nice viv btw!
