So what you are saying is that there is a possibility 50% and over of
jills with prolonged oestrus will not develop aplastic anaemia.
 
These days to be fair to my jills if I do not intend breeding from them
they are put in with one of my vasctomised hobs, so they do not have a
prolonged oestrus in any case, should they come back into oestrus a
second time they are put back in with one of the vasctomised hobs.
