Comments on another thread prompted me to start this thread. Is there any truth in the saying that chestnut mares are temperamental?

I'm not at work so can't access the pubmed articles based on human research and I can't seem to find the cross species study on google.
The research has been done and it has been biologically proven. Some 'red heads' may handle stress better as they have developed coping strategies. They will still have high serum cortisol levels though that show the physiological response to stress.
It's not 'discrimination' as someone on the other thread said - it's biology. Knowing the biology allows us to help our redheads
Eta - it would be interesting to know whether heterozygote blacks show higher stress levels due to having one 'red gene'
Thanks. I'll take a look. I know some red cocker spaniels can get rage syndrome. But I was thinking about horses. What about bright bays? they are very red.
It's not the colouration as such but the gene combination.
Eta - it was actually the 'rage' issue that originally started the study and it got expanded to other breeds and then animals.
That research is on wild boars. If it's the gene combination then it could not also apply to horses because different genes are involved in their colour than for wild boars. I think it refers to the colour pigment having a particular chemical make up. It may be that the pigment may be the same chemical across species, I don't know.
Interesting thing to note - red-headed people have been proven to experience pain differently from non-red-headed people. It has been linked to the 'temperamental red-head' myth.
Looking back further than I want to admit, I would say that the red heads are more likely be sensitive than the other colours, though of course there is a big overlap because of all the other factors involved.
That sensitivity, in mares and geldings, in my experience, produces more nappy or temperamental horses than those of other colours, and if you add the additional sensitivity of a mare into the equation then I do believe that a chestnut mare is a bit more likely than any other colour to give the owner some issues to deal with.
But that only means that two in a hundred chestnut mares have to be tricky, compared with one in a hundred bay mares, for them to be twice as bad.
True black (no paler hair at all other than white markings) horses have a reputation in some places for being exceptionally stubborn. I wonder if that one is true?
