She looks great! I understand your pain as 3 of our sport ponies have long feathers that are always disgusting and gross. People usually make fun when they wear jumper boots and look silly. When we bodyclip, we leave the feathers on (required by the owner). I was so tempted to clip them off, but I couldn't I don't have any issues with staining, but I used Orvus shampoo on them and wash them every day (comb them, too). I know this sounds extravagent! But, the result are ponies with soft and white feathers.
