I have to say I have a chestnut mare, and she is the moodiest female I have ever come across in my life!! People tell me all the time 'it's a mare thing', or 'it'sa red head thing' (i'm a red head as well!!) Although I must say I've met equally as moody appys, bays, browns, paints and any colour of the rainbow... I think it would be an old wives tale, but it definitely applies to me!!
