I own 4 coturnix quails. 1 is named Cotton Ball, who's perfectly healthy since she lives inside my home. The other 3 live outside and are sick. One is named Pine, who's somewhat elderly and female. Today, I found her belly completely void of feathers, revealing a black belly underneath, it looks like it's rotting and feels kinda rough. Her breathing is strange, it has a rattling sound and sounds phlegmy. She isolates herself in corners and is pretty weak. Her breathing is a bit labored and she sneezes. My male quail and another female are a bit better off than she is (Cactus and Lemon), though they sneeze sometimes and also have a rattle to their breathing, so they may have been infected by Pine. There isn't a vet nearby that can treat anything outside of dogs and cats and I can't even afford it anyways. Anything I can do to help my babies? Here's a picture of Pine's belly that I took on my phone. PS: I'll look into tips used for chickens too. Anything would help at this point. I want to save my babies.
