Hello everyone - I'm relatively new to chicken keeping and just got my first hens this past spring. Last week, I acquired 4 new birds, reported to be two Araucaunas and two Marans. They are different ages, probably ranging from about 4-8 weeks. They came from a large barn with a variety of chickens/rabbits/turkeys/peacocks all mixed together. The conditions were not what I would consider "ideal". I do have them quarantined from my other birds. They all seem fine,and I don't see any signs of mites or lice, although I'm not entirely sure what to look for. On of the Marans, however, has a problem with it's right eye. It appears swollen and partially closed. The chick is not sneezing or coughing or showing any other problems. The first three pictures are of the affected right eye. The last picture is the left eye that appears to be normal. This site has been very helpful and helped me to tackle the endeavor with some confidence. I'm sorry if this is already posted somewhere, but I searched and couldnt find anything that seemed to fit completely. If anyone has any advice or input to offer, I'd appreciate it. Thank you!
