trying to down load a pic but not working right now......possible pox dry, lg. scab on hens ear lobe, ...I have ordered vaccine need to know if any one has delt with this, do you separate possible cases or not, she has had this scab for at least a month so they have all been exposed,,,,,,,, don't know what this is, some of her sisters have had rough skin on legs, pink streaks going up so I treated with penicillin thinking it is an infection. ear lobe is also swollen,
