I have a filly who will be 2 in may. She is a TB/Andy cross (mom is bay, dad is black) and she is RED!! When she shed her baby fur (which was a creamy read) and grew in her fiery color, she also acquired a white spot on her rump. It seems each time she sheds (summer to winter, winter back to spring..) a few more white hairs show up randomly on her body...right now, the white rump spot grew another spot next to it and she has some roaning in her flanks.
Do you think she will eventually grey out or just have this pattern? If it helps, last week was the first time I noticed white hair in her mane as well. Thanks!
