After 18 years of being horseless, I know have 3 horses. Basically all rescues. The one mare and the gelding we have had for 8 months and 6 months respectively. The mare has always been of an Alpha mare personality and would boss all the other horses she was herded with previously and bossed the old gelding we got 6 months ago. Just this past weekend, we purchased another gelding who is about 3 1/2 years old. He left our other gelding alone, but kept challenging our mare for dominance. In the past week, it looks like he has won as he chases her away when we feed them until he gets his food first. Now, she doesn't seem happy about him, but seems calmer in a way. I know this is probably a stupid question, but I have never had three horses before. I only had one when I was growing up and we boarded a pony for a few months, but never was able to see herd dynamics in action. Is this normal? Will they eventually work it out amongst themselves? I really would like for the mare to calm down as she always seems to be on high alert and can be a real pain to work with, yet I want her to be happy as well, or am I just anthropomorphizing them? I really don't want to have to rehome the new gelding as I can see he has already had a rough start in life from the scar on his face and neck like someone has either lassoed him, bridled him tightly, or whipped him. They are not biting or kicking at each other, he just lays his ears back and walks towards the mare and she walks off. If we try to feed her first, he will chase her away from it, but won't bother the older gelding.
