I'm working on a project for grade Percherons, (mushroom), and because it'll only show on non-black coats, I'm going to need some bays or chestnuts - but! Because of what I'm planning to use the grade Percherons for, and because of my own personal rules for that breed, that the only acceptable red-based coats are seal and brown bays, it... obviously gets a bit harder. (I've seen plenty of regular bays, but only a very few with At)

Requirements: Not visibly inbred, agouti gene has at least one At, extension gene has at least one E

Preferred: Not inbred at all, AtAt or Ata agouti gene (or aAt if the ordering's gone weird again), EE extension gene. Not related to my own Percheron lines.

Doesn't matter: Literally anything else. BS, PS, age, level, number of foals

I'm going to need a lot of these, so this request's probably going to be up for a while. I'd prefer to pay in bits, but can spend some ingots if necessary. If anyone's got some they're willing to sell, please let me know!
