My birds are looking scruffy lately, espically my roo. They are getting layer feed, oatmeal on cold mornings and I have been putting avia charge in their water at least twice an week. But they seem to be losing a lot of feathers and their "coats" are just not looking very good. I was thinking about crushing up a multivitamin and putting it in their food. I havent done it yet, wanted to get some advice first. Thanks!
