Our baby chick has a brownish-black toe

[chickwish]

Would like some advice. We just got six 2-3 week old baby chicks, the day after we got them, we noticed one has a brownish-black toe nail and part way up it's toe. It's not swollen, the chick is acting completely normal! Eating, drinking and running around. I don't know that much about chicken diseases, but after googling I'm worried it's bumblefoot? Last night we soaked it in Epsom salts and warm water. Can someone help us out as to what it might be and the best way to treat it? (I've tried like 10 times to attach a photo and it says "image cannot be loaded from passed link"...not sure how?!)

Thank you, I didn't see that before! I attached a photo now. Does anyone have any advise on what this could be on my chick's toe/nail? Not swollen, chick acting normal not limping, and eating and drinking like the others.
