Chicks like that go into a tea cup so that the yolk is not ruptured by the other chicks.okay here goes three others have pipped this is just day 20 Thank you View attachment 2150877
When the umbilical cord is dry you can cut it off if it does not absorb. You can cut it earlier but it might bleed and would need to be tied off with thread or dental floss if so.
The chick should be fine but will be hungry since it did not completely absorb the yolk
