A couple of days ago I noticed our 7-10 week old cornish x chicks had black bruise like spots and knots on ther necks and chest. I went through all of my books, googled, googled, and googled some more, called some vets and find NOTHING! They are acting fine, eating, drinking, playing, but they look terrible. I'm now seeing large areas on the shoulders (?), where wings are attached, with black scabs, as if the flesh has been eaten or rotted. Any info would be greatly appreciated. I am seriously sick over this and am having some wicked nightmares!!!
