I have a black cochin bantam pullet (around 6 mo. old) who lives out in my barn. When I went out to check on her this morning, the area around her eyes was very pale and puffy. One of her eyes was also crusted shut. I cleaned off her eye and made sure that there was nothing physically wrong with the eyeball. She naturally has fairly pale combs and waddles, but they looked especially so this morning. I've heard a little bit of sneezing over the past couple of days as well, but at first I thought it just might be dust etc. Are there any possible issues/ ideas as to what she has or needs? FYI-- it is fairly cold outside here. It is averaging around 30 degrees Fahrenheit in my barn. She has access to warm water and chicken feed. She lives alone. Thanks!
