I’m saying it’s Marish because I’ve had geldings for decades so it might be just her. I’ve had her for 3 months and she’s a lovely steady ride and can be soppy and gentle. However, she throws her considerable weight and size around at feed time and in the field. In the morning I will go in and fetch her hay net and buckets and she’ll be charging across the stable or over her stable door pulling the most awful faces and trying to bite her neighbours. She doesn’t do it at people but she’s not very respectful of space. Same at night and in the field if you go in with them (her and 2 ponies and a donkey) she’ll run at the them and kick out to keep them away from me. I have a 10 and 13 year old who ride and have been used to just going into the field with their ponies but they can’t anymore. Her previous home was on livery. She was given lots and lots of treats so is always looking out for food and if she did pull her face she was shouted at. Is there anything I can be doing with her. I’ve been keeping stable routine efficient at feed times and working on backing her up, not adverse to giving her a growl and squaring up to her but is there anything else I could be doing. I’ve been searching for horse behaviour videos online but not found anything relevant So far. Thanks
