My girls didnt want to go in today when it started raining...so my little Snowball (White Polish) is now Mudball. She cant even see there is so much mud weighing down her head feathers. Can I wash these or trim them off? And if so how? I have a total of 6 Polish and most cant see well due to the feathers in the way... but Snowball used to be ok now with the mud on her she is just a sad little mess. Any ideas?
