hmm.. i was actually going to post a topic about this..
at the barn where i work, we used to have this gelding who would always eat a certain mare's manure.. every time!! this year, we have noticed probably 5 or 6 of the other mares and geldings also stopping to eat this certain mare's manure as we were walking on the trail... what gets me, is that, they ONLY eat THIS particular mare's manure. they show no intrest in anyone elses... but when this mare makes manure, everyone stops for a bite... this mare gets no other dietary extras than any of the other horses... all 21 of them live together as a herd 24/7... any thoughts as to why they only eat this horse's manure? .. its baffled me forever...
