I got my new mare 2 months ago, she's fab. She's in a very large paddock with one of my landlord's horses as a companion. I've arranged with my landlord to feed his horse as well as mine (he offered to have one of his worker's feed them both once a day, but my mare gets garlic and another supplement, so I thought it was easier to do it myself...plus I don't mind!). I feed them in the AM before work, and then in the PM. Everything was fine until this week. They would previously eat out of their respective buckets quite contently, but now the gelding has shown a bit more agression, and more interest in my mare's feed. He usually takes one bite of his feed, then moves on to hers. She backs away without much fight. Other things you should know: My mare eats Triple Crown, which I store in my house. The gelding eats a generic sweet feed kept outside by their paddock in a metal trash can which leaks. I presume there is a combination of issues, one being a dominance thing, the second being that his food is not nearly as pallatable. My landlord is super nice, and super rich, but also super lazy I bought a new trash can today, and went to his house to explain the leaky bin. I informed him that his food is spoiling, and I'm happy to keep his feed at my house. I think this will help eliminate part of the issue, but I don't expect it to solve the agression/dominance. I am a little hesitant to suggest he switch his horse to my feed! He's got 5 others kept in another paddock. I don't want to be super fussy, but I could possibly ask that he give me another horse to keep my mare company. Before I make other suggestions to my landlord, do you have any ideas?? In the evenings I could seperate them for meal time, but i'm always running late for work(!) in the mornings, and would rather not deal with the hassle...I want to ensure she's getting her feed, the right amount, and also not tempted by his nasty sweet feed bucket which is left unattended as he devoures hers! Thanks, and thanks for reading!!
