We moved about 3 weeks ago to a beautiful 11 acre farm, and we decided to turn out our 3 full sized horses (2 geldings, and my mare Roxy) with the 2 minis the old owners left us (1 mare, 1 gelding.) Our full sized geldings were turned out together where we boarded, and they had both been turned out with Roxy a handful of times before on show nights, as well as being ridden together etc. When we turned them out together they were fine; a few bites and kicks but nothing unusual for horses who haven't been together much. They also get along great with the minis, so fortunately no problems there.
However, they're all getting a bit herd bound. Plus the two big boys are completely attached to Roxy. They'll follow her all around the field and kick at each other if they think they're trying to take their mare. We currently only have one field and a ring because the other big fields are being hayed (we're going to talk to our neighbor who cuts it this weekend and tell him that we will be needing them. They should be cut in a week or two I think.) so it's difficult to keep them separated. We have a barn, so I've been trying to bring Roxy in for a couple hours away from them during the day, then at night I turn her out by herself in the ring so they can all see each other and smell noses but there's some space there. Also, she came in season a few days ago. Normally she's just a little more high strung, but this week she's been "squirting" and squealing and prancing all around the field. She used to be in a field next to geldings, but still separate from them.
So my question is, do you think the herd-boundness and Roxy's obnoxious mare behaviors will resolve with time, or is there something else that would help them? It's a manageable situation, but we want to be sure we're not creating bigger problems. Thanks in advance!
