That was really interesting, who would've thought it was that way with horses. Animals are way more intelligent than we humans give them credit for.
I've learned by watching all the deer we feed, some have been coming for years, we get to know their markings. Anyway it doesn't take long to see who is the alpha doe and the alpha buck. I find it fascinating to watch the hierarchy in the wild, it always amazes me how the others submit to the alpha.
