Rug ripping update and another question

[WeeBrown]

Thanks for the advice last week about whether the rug ripping appeared to be the other gelding and what to do to limit this - we ended up making sure there was lot of hay in lots of little piles but this hasn't seemed to help so we are now having to split the field.
My OH actually saw the other horse chasing my gelding, biting at his rug and my gelding did not look like he was enjoying it. Then today someone came to get me to tell me that my mare was being chased by this horse

He usually doesn't bother my mare other than to herd her away from fences and move her off hay but I was riding my gelding at the time so this gelding must have got bored even though I had put out haylage. When I went to bring her in a few mins later she had a cut leg

On a different note is it possible for a gelding to get more aggressive as it gets older? This gelding used to get on fine with both my horses when we were at another yard although he did play fight with my gelding there and I have been told he ripped his rugs (my gelding wasnt owned by me then). But since coming to the new yard this other gelding has changed in my opinion. He runs at fences, YO thinks he has kicked her horse who is in the adjoining field, I have seen him try to mount a mare in another field that adjoins ours (he got caught up in electric fence that time) and instead of just moving my mare off hay he has now started trying to kick her. He will also spin round and either kick or strike out at us. It's a real shame as I did like sharing a field when we were at our last yard.

i absolutely would not turn my horses out with him, for their sakes!
yes, their temperaments can change, they can develop into bigger bullies.

Your YO needs to do something to separate that horse before a major accident happens. Sorry but we had one like that at our old yard and it was a miracle it didn't kill either another horse or human.

It is possible for a gelding to get more aggressive as it gets older. Just like any mare or stallion could. But unusual. I wonder whether this horse is in some kind of pain for his behaviour to have changed so drastically. Or if he is bored in the field because of the recent weather?

Thanks - we are splitting the field next weekend with post and 3 rows of electric tape. At the minute my little gelding is in a small isolation paddock and mare is inside but I might have to rotate the use of the small isolation paddock this week or see if I can put them in a small temporary paddock that YO uses for her horses. I had hoped that the rug ripping might be all that happened whilst OH was away in america this week as at least rug could be replaced but my mare's legs are more important. I'll just have to see if maybe an instructor on the yard can ride her during the day if I can't get her another paddock short term.
