I'm sorry that the baby's hurt
Never would I take her to a bird shop for any reason. TOO much chance of disease from the commingling of birds from multiple sources and too much chance of a stress crisis that only a vet can save her from. Two stories behind that comment, but just trust me and don't take her into a bird shop.
My birds are flighted now, but in years past, I trimmed them myself. It's so easy to take just a little, see how much altitude they get, and trim more if needed. PM me if you'd like more information re my technique.
I surely hope her foot is just sprained and she heals very fast.
