What store did you get her from? If it was a Petco of Petsmart, don't trust a thing they say. They don't know what they're talking about haha.
If it were me, I'd have something down. Even though the "normal" picture makes her appear skinnier, I'd still be cautious for her age.
"He" doesn't have spurs, the casque is small, and the coloring seems more in line with a female. Sorry buddy, you probably just gained a lot of stress haha. Females are worrisome! They're all rewarding of course, but there is additional stress with females.
And no problem! I just so happened to be browsing the site when you posted. Happy to help.
