Wow, this is almost an impossible question to ask. A silver buckskin, dunskin and buckskin can all look exactly the same as a foal. So there really wouldn't be an exact science to "recognizing" one as a foal. You would be best to know the genetics of the parents and what they may possibly throw or when in doubt, you test. A silver buckskin can be born with an all white tail or mostly white tail as can a buckskin or a dunskin. They can all be born with dorsals and leg bars...clipping might help to determine what a dorsal looks like under the baby fuzz but then, you still run into the problem if it is a real dorsal or countershaded dorsal. The number one rule to color genetics is they are never exact and there is always exception. There are some factors that tend to stay PRETTY true but not always. I have seen buckskins, genetically tested to NOT carry a dun gene have VERY good dun factor type marks. I have a positive tested dunskin MFT filly who shows no dun factor at all she is so light, the only way I could be sure was to test. And as you have seen with some of the photos posted, there is always an exception, for instance, the filly born that looks exactly like a silver bay but has shed out to be a silver buckskin so who would have thunk...? I am a big believer in testing, other wise the best you can do is a good guess until that foal sheds off some...but as far as the learning to decipher...anything involving cream or silver on a any base makes a lot of things confusing lol such as diluted marks or false marks etc. If you know your sire or dam carries silver and the foal has a lot of white with chocolatey points then you can guess most likely silver buckskin. If you are suspecting dunskin but neither parent carries dun, then not a dunskin. If you do have a parent that carries dun, sometimes you get a buckskin baby with very loud dun factor, sometimes barely any that is more visible after clipping or the first shed, sometimes the dun factor is so diluted by the cream gene it is never really visible. Aren't color genetics awesome!? Love them.
