Recently my 13hh exmoor mare is in a really bad mood. She no longer whinnies to me in the field, she is being really grumpy to our other mare (She is usually really sweet) and she is biting when i put her rug on, or simply go into her stable to say good night or give her a hug. This has been going on for about a week.
I am not sure wether she is just in season, or if she is feeling ill, or just in a bad mood?! I am scared to use mare-ish behaviour supplements in her feed, as this is incredibly un-usual for her to act like this, and as i am at school at the moment, she is only being ridden 4-5 times a week.
I did wonder wether her diet is causing problems - we have cut down her hay from 3 sections to 2 sections, and she is having half a scoop of feed less.
Any tips/help/ideas please?
