My family's little Bantam Cochin hen, Pumpkin, seems to have a cold or something. When she breaths, her breathing sounds like it's rattling and her nose sounds like it's full of mucus. Her eyes are bright and normal, there are no bubbles or anything. Also, her nose isn't runny. It's completely dry. Her feathers look fine, her face isn't swollen or anything...The only thing that gives me the idea that she's sick is because of her wheezing and sneezing. I think she might just have the common cold. I don't think it's Infectious Coryza, because her head is not swollen, she doesn't have a runny nose, she doesn't have bubbly eyes, etc...Overall, she looks and acts fine except for the wheezing and sneezing. Help! How can we help Pumpkin get better? Thanks! P.S. her droppings look normal too, if that helps.
