hello one of my hens an approx. 18 month old barred rock has been going through what seems like a molt over the las 3-4 weeks, except it is only on the front of her body and none of my 5 other birds are molting. Up until today she has been fine except for the fact that she has almost no feathers on her front and around her crop looks pretty red but it isn't bloody. However there arent any pinpricks of feathers growing back. Today about ten minutes ago i went out to collect eggs/ make sure the feeder was full. I noticed her out in the run with part of her neck all red with a little blood. It also appears that there is a smaller healed one on the opposite side of her neck. However she appears to be interacting fine with the others and she isn't being picked on see picks below. Oh and i have separated her from all of the others and i have no rooster. How should i treat her neck?
