I'm a first time incubator. I incubated 11 eggs and only 1 hatched. It hatched great yesterday afternoon and seems fine now. I just moved it to the brooder. It's chirping and pooping and walking around. The poop is green though. Anyway, it has something hanging off of where umbilical cord was attached. It's starting to dry up now. Is it something I should be concerned about or will it fall off?
Thanks!

Thanks!
