Sorry but I would never tie a mare up and leave the stallion loose! Too dangerous - if the mare decides that she is not in season and the stallion becomes 'annoyed', a fight could start and make it impossible to untie the mare. A mare should always be able to get away from a stallion if she is not ready to be covered/is no longer in season in my opinion - she should have the room to be able to tell the stallion to clear off and leave her alone without injury to herself.
If you feel that your boy's lead rope is not long enough to keep you out of trouble from possible flying hooves, then use a longer one, but i find a normal lead rope is just fine because if the mare looks as though she's gone past standing, then I just walk the stallion away - it never gets to the kicking stage. Bree is a very experienced person and knows her animals well, and her way of doing things obviously suits her, but I would always have the stallion on a lead and taken to a loose mare if I had no help - I would rather have the 'troublesome' one under my control!! LOL!!
