I have a 4 1/2 yr Spanish Barb mare 2weeks ago we let someone bring their gelding to the barn to bored. The problem is I have goats and she thinks they are her babies. To the point that last spring she started producing milk and trying to steal the newborn kids. How do I get her to stop guarding the goats? I can't keep her locked up at this time and the goats need to be able to go in the pasture. Right now she tries to herd them all up and keep them in the barn so I locked them up in the new stall. (Brand new barn. We have the run in finished and 1 stall done.) Since they are locked up she stands guard by their stall and won't let the gelding in the run in or if she does doesn't let him near that side. How the heck can I break her of this because I do want to get another horse of my own so my DH and I can ride together.
