Almost a 30% chance of either Buckskin or Bay, 16.6% chance of either palomino or chestnut/sorrel, or a 4.2% Smokey Black or Black. Hard to tell in this light, but I'm thinking she's going to be a buckskin -- a color like the inside of her ears, and this darker fluff is just a "smutty" baby color for natural protection! We can tell more once we see her in the daylight!
Looking good, and I love the new pictures!!
