>Could the problem of aplastic anemia be in the way that ferrets are kept?
 
Aplastic anaemia is a recognised medical condition and have nothing to do
with how ferrets are kept.You must've brought your jills out of season by
either a jill jab or a vasectomised hob-seeing that you don't believe in
neutering/spaying.
 
"The high levels of endogenous oestrogens produced,may lead to
progressive surpression of the bone marrow.If this occurs,the production
of all blood cells is affected,leading to leocopenia,thrombocytopenia and
aplastic anaemia.All jills will develop at least a mild anaemia during
oestrus(when in season) at some point,and up to 50% of jills with
prolonged oestrus will develop aplastic anaemia."  (Source for this

Why do you seem to think that the way ferrets are kept,could lead to
this? I can see no relevance.
