We have a Barred Rock who has lost the feathers on her chest and bottom, skin is red biut it doesn't appear that she is being pecked by the other chickens. The other Barred Rock's are fine, we are new at this so any advise is appreciated. We also have a few RI Red's who lost some feathers by their tails a few months ago and were pecking themselves. We started using Schneiders Herbal Solution which has stopped them from pecking and cleared up bleeding/scabs but the feathers have not grown back yet. How long does it typically take to grow feather back. Are the online bird vet's legit?
