EMERGENCY - chick born with a yolk sack - it burst, is there any way to help?

[WoDia]

Sadly the chick passed away this morning but the other ones are all doing fine, they were pratically all born at least 1 day apart, (one has been born for 4 days!) And we had to take the younger chicks in with us til theyre stronger

I’m so sorry to hear. He/she had a rough start. Give extra cuddles to the others. I hope they do well. Keep us updated.
