- This is about my chick ruby who already is believed to be a roo-by. She's about to be 2 months old and I'm noticing that he has what looks like tiny fuzz comin through between the scales on her little feet? Is this bad? The other two pellets do not have this only ruby. Mind you she may be a roo but I can't completely tell yet, even if she was I didn't think buffs had feathered or fuzzy feet whether they are a roo or not??? So my question is why is this happening and do buff Roos have feathered feet ever or is this a diseas or something
