My daughter's pony who we have had for about 3 months has upto now been very calm and laid back but with the arrival of a new gelding in the field next to his he has become bossy and very protective of the mare who he shares his field with. He has had to be moved to a field with another gelding because the owner of the mare has found it very difficult to catch her mare without our pony causing problems. Do most people keep their mares and geldings seperate? If not how do you avoid the resultant problems of mares in season and geldings fighting over the mares.
