Hello Everyone! I built my own barn 3 years ago and while I am a 30 year horsewoman...I am learning many interesting things when you only have 2 horses! It started with a buddy sour horse who finally had to be sold. I have had two together now for a year and they are great. Attached at the hip but both are able to be ridden individually with no problems. I have a third stall and recently my friend bought a gelding (my two are geldings as well) and moved him here. His name is Danny. Everyone got to meet in stalls next to each other. Turnout is fine with Danny and my horse Roux. However, my older horse (23!) seems to think he can only have one friend, and is very, very aggressive towards Danny. Whether it is just the two of them out, or all three of them out, Marquis wants to chase, bite, kick. I have 8 acres of turnout and my husband says let them sort it out. I agree to a point but the chase continues too often for my comfort. So now I am separating Roux and Marquis to see if I can break up this bond a bit. Roux and Danny out at night. Marquis and Danny out during the day. Separate fields would be great but expensive especially with having to get an additional shelter. Has anyone with only two horses had this much trouble introducing a third????
