My daughter got her first horse in December a 13 yr old mare who is 100% in every way, or so we thought until we turned her out in the field!
When we try to catch her she is very aggressive (biting and kicking)towards the other two horses in the field.
Someone on the yard said it may be because she is in season, ( how can we tell if she is in season)
If this is the case has anyone any advise on what we can do. Her tempermaent is fantastic except when in the field.
