I really have never had regrowth until molt, but I have not ever done much about it. Usually, before molt the feathers are old, and they look worse and worse, then molt in which they look like they have some hideous disease, and then the winter, rooster sap sinks down and beautiful feathers come back!

You caught me off guard with that one. I’ve never heard it, but I think it’s the funniest thing I’ve ever heard.
