Hello everyone I'm new here and I'm hoping someone might be able to help me out. I have a 8week old female sex link who isn't doing very well. We noticed that she was very lethargic and it seems like she is gasping for air. She makes a chip sound, and keeps her eyes closed. We've separated her from our other chicks who are all the same age but showing no signs of sickness. I haven't noticed any poop from her, but after giving her some fluids with a childs medicine syring she throws/coughs up a brown fluid. There doesn't appear to be anything in her crop, but it does feel like an air bubble... I'm not sure if that's normal as this is my first experience with chicks. Any suggestions, and all help is very appreciated!
