My two adults have lived together amicably all winter after an initial 'sort out' of heirarchy when they arrived. The goatling accepted second place, and all was peaceful with the occasional scuffle to re-assert first place.
A week before kidding, they were separated by a hurdle with access to their night pens which are also only separated by a hurdle. So they were in constant sight, smell, reach of each other. For the last two weeks I have been putting them together for supervised access to forage rack etc and, while hungry and absorbed by greenery, all is quiet. Then a head-butting battle begins with mad chasing and clear aggression from the older (former dominant) doe to the younger, who now stands up for herself more.
The older one's boys are being bottle-fed and do not get turned out with the girls. So I don't think protectiveness is a factor as far as the aggressor is concerned. In all this, the female kid of the younger one gets knocked sometimes (which doesn't seem to worry her but I keep thinking about broken legs etc) and I always separate them again before I leave them unattended.
Is this usual? Should I keep them separate or leave them to sort out their position? Would it be better to wait until the kid is older or would that just make her more of a target? I'd like them to be a unit again but don't want to risk injury to any if time is needed to let things settle down.
