On inspection of our chickens today we noticed that Olivia (our 3 year old's favorite) has some severe skin issues. We have inspected everyone else and no one has even the slightest deformity/or feather missing. She eats good & is not acting sick. Anyone know what this is & what we need to do for poor Olivia? I know this is a terrible pic but she is really raw, red & scales. She also has what appears to be a round wound/hole under her wing.
