hi,i have 2 spur thighs , supposed to be a boy and girl,the one they said was a girl is chasing the other one and really butting/biting then mounting it , do girls do this ? the one they said was a boy is forever trying to climb the sides of the outdoor run, should i seperate them for part of the day to give them a rest ?they only do it outside not when we bring them in at night in their table
