I have two Old English Game hens that are blue in color. Both have feather loss and feathers that seem to be thinning out. Just recently both have practically lost all of their tail feathers at the same time. Does anyone know why? Is this normal molt or does it have something to do with their blue-ness. I know the "blue" gene is some animals can create alopecia. I have 5 other bantams of differing breeds and none of the others are having this problem. I should say, by blue OEGs are older than the rest by a year and are probably the top dogs of the group, so to speak.
