I found my 20 week old cockerel standing on my porch in the dark a few minutes ago. He was standing there completely still, and kind of maybe gasping for air every 3 to 5 seconds. Also, his voice isn't working. He actually voluntarily showed me his throat, opened his mouth toward the flashlight and everything (that's how you know they're really sick...when they get cooperative ), but i couldn't see anything in his throat. His crop was full because he recently had a big meal, and i massaged it for a while until he stopped gasping for air and started to breathe more normally. But his voice didn't return. This all came on very suddenly, so i don't believe there's an illness. But i'm just very curious what could be stopping his voice and if any of y'all have experienced that before. It's definitely a new one on me. How can the crop affect the breathing and the voice? As it appears is happening.
