I came up with "Hell Coulee Toppers I Am Dun", as I truly think he did get his mom's dun gene, but it's so faint on this combination, it can be hard to verify.
Need to get back out and get to work on the rest of my chores, I've only fed the bottle calves so far, but...
If she took, Misty is minimally at 300 days (she could be upto like 30 days more, but I'm leaning more towards, the end of the turn-out time that he may have caught her, if he did, cause she doesn't look overly pregnant). They haven't had enough foals to get a major broodmare belly, so they seem to carry high and tight, plus our crappy hay still has them thinner than I'd like to see.
