This took me a long time for no reason.
Indont know donkey gentics but I know equine so I'll use those.
Dam: slate dun spotted (Ee as DD To)
Foal: "charcoal" dun minimal spotting (EE as D To)
These lines are adorable and I am in love with donkeys and mules. They are my favorite!
I plan to make a few more of these. Here are my ideas
Extreme dun
Pearl foal with brown dam
Flaxen chestnut
