I'm so devastated, my favorite 5 week old chick is really really sick- I think she is dying. She was just sitting hunched up in the brooder, and didn't protest at all when I picked her up and carried her into the house. Her crop is really swollen and feels gassy and liquidy. I tried to massage it and help her throw up- based on advice I've read for sour crop. She did throw up a little, and i gave her some water with acv, but then she did a couple flops, I was holding her, and a little dribble of white pee/poo came out and now she is laying there on her side- eyes shut, barely breathing. I'm almost positive its too late. Was that sour crop, or something that the other 3 chicks in her brooder might get?
