I have 2 two week old chicks; one still has a crusty bump on its butt where its umb. Cord was attached. The other chicks' was gone shortly after hatching. Should I be concerned and what do I need to do to treat it. It doesn't look infected or smell its just there. Thank-you.
I would leave it. Just like with real (human) babies, those things fall off when they're ready. Everyone progresses at their own rate.
Ya, don't mess with it. I've had some hatch with open navels like that. The end with shrivel up and eventually fall off. Messing with it can open it to infection.
