I also have a beautiful white crested black Polish rooster, the "free exotic" sent with my mixed group of pullets, all together since shipped out on day of hatch. At about 10 weeks the pullets started picking at his head, and really bloodied the poor boy. I cleaned him up and put some antibiotic ointment on his head, tied his crest feathers into a top knot with tiny horse-braiding rubber bands. I have had to shampoo him about 3 times (with baby shampoo) and fix his hair-do, also tried putting some "Rooster Booster" on his head (anti-picking remedy available oneline). This has worked well for me. He's starting to exert his masculine authority now at 18 weeks, and perhaps will be able to go au naturale in the future... not sure. When I first posted about this, I read lots and lots of postings about the problem with mixing Polish with others. Even when they have lots of room.
