Prior to the move the mares did not care for one another, but were turned out in the same herd, and stalls were nowhere near each other.
Since the move, the mares get very upset (calling/anxious) if they are separated. They are now stalled across the aisle from one another, as well as turned out together. They can see other horses from their pasture, but are not pastured with any other horses. They are getting difficult to lead or separate even for short periods.
I expected an adjustment period (it has been about 9 days), but not sure how long, or how we can help them other than what we are doing.
What we are doing is keeping a consistent schedule, expecting decent ground manners correcting when necessary with circling, backing (which has never been an issue until now), talking in soothing tones when they start to get upset.
Any other suggestions, Ideas, or words of wisdom?
