Bought some chickens from IFA this afternoon. Had them in a cardboard box while I adjusted the brooder. When I went to move them I noticed one isn't feeling well. She's puffed up with no energy, and her crop was empty. She's breathing hard and fast. I gave her a small heating pad that I've used with my other babies in case she was cold. A little while later she began wheezing very loudly for about ten seconds at a time. It's only happened maybe three times so far. Poking some sugar water down her seems to have perked her up ever so slightly. Not much. That's when the wheezing began. I used the same method I've used before when I've had sick chicks. She did get the energy to take one poke at the food and clean a feather. I know wheezing is NOT a good sign. What's up with her? Her buddies are all fine. What can I do to keep her comfortable? She's a little smaller than my palm currently, not sure of age.
