One of my 3 day old chicks has a lump hanging out of her vent. Belly feels like it's still full of yolk or something too. She's active, but not as much as the others. I gave her a couple of days to see if there would be improvement, but no. So tonight I used warm water to soften it up and see what I could tell. It did soften and I was able to pick off what almost seemed like egg membrane. There was a little poop in there too, but even after the membrane came off, there was soft pink tissue sticking out. I'm thinking this does not look good. Any thoughts?
