My best show hen got attacked today by a dog. Lots of the Wong feathers got pulled out. How long will it take for the feathers on wing to grow back? I have a show in march.
Feathers often do not grow back until the next molt. Every chicken is an individual, but that is the usual way it works. Especially if there are any feather shaft tips still in there, the birds body still thinks there is a feather there. Nothing much you can do but wait. Sometimes they will grow back sooner, but no guarantees.
