black toenail

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...

Hello there, We are newbies and just noticed our 6 week old golden Sexlink has an injured black toenail or toe. It doesn’t seem to affect her, she doesn’t limp or appear to be in pain, should we be concerned or treat it? We live in Texas, so no frostbite issues. Thanks for any help.
