so i have 2 rouen ducks and they are both starting to have little specks or green on there heads. and we think they are males becuase that is what someone told us. but we only have 3 girls and one of them is already hurt so now we are not sure what to do. should we keep the boys or get rid of one or both? we dont want any of our hens getting hurt so what should we do? please help!
