Hello, I've noticed that my beloved Vorwerk hen, Lady Egglantine, is growing spurs or something. I have no clue what they are. She's had them for a couple of months now and, slowly, they're getting longer. So, I have a few questions: 1. What are they? 2. Will they injure any of my other chickens? 3. Should I remove her leg-rings? 4. Will they harm her in any way? 5. Will she become aggressive? Thanks for any help.
