She is a very lovely girl, she appears very healthy and of good condition. Congratulations on finding her!
I know what you felt like at that show. A few years ago, I had saved money enough to buy a certain morph that I wanted, a female. I went to a reptile show, I got there very early and waited in line a long time. I was so excited and eager. When I got inside, there were many of the morph I wanted, but all males! I was so very unhappy. I had money, I was there early, why did no one have what I wanted? So I decided I would not just buy anything, I knew what I wanted. I looked and looked and looked, but no. All males. Then, as I was getting ready to leave with no snake, a man who was late to sell started putting out his snakes. So I decided to wait to see what he had. I waited and watched, and then...he unpacked two of the snake I wanted. A male and a female! I asked to see the female, and she was so beautiful! I just knew I had to have her. When I asked how much, he wanted just what I had to spend. So I bought her. I was so very happy.
Can I ask, do you feed live or frozen? If you feed live, go ahead and offer the new girl food. If she does not want it, you can offer it again later. If you feed frozen, I would wait until next time so as not to waste the food.
