I wanted to see what you all thought about one of my baby's bums. When she hatched she was covered in yolk but naval shut and she made it but her bum remained huge and spongy. I thought about possible infection, maybe from bacteria getting in but from what I've read, that usually kills them a lot sooner. This baby is 5weeks old now and still has an abnormal looking bum. It's spongy, and even kinda crunchy feeling, and when I hold it, it feels twice the weight of it's normal looking siblings. It acts perfectly normal and active though. Any ideas what this could be?

It is probably a form of mushy chick disease but as @Sally Sunshine says, MOST chicks die, not all. I've had one that had a large sack to one side of its vent , it is about 12 months old now. I guess you will just have to wait and see whether or not this has any long term health effects.
