We don't usually do anything different for our first time Moms.
Just watch them during the pregnancy to make sure they stay healthy, and keep eating food/water. Also keep them in as low-stress situation as possible.
I haven't found anything yet that really increases their odds of being good moms....either they will be, or they won't, and there is not much I can do to change it either way.
(Except maybe breeding for good temperament, and good hips/hindquarters in my brood does).
It wouldn't hurt to put a little extra fur in her nest box, but it probably won't change her mind.
When it is cold out, we usually try to use a heat lamp or heating pad for our first time moms that we do not trust yet. (But use them CAREFULLY!)
Don't worry to much. The vast majority of our first time Moms do fine. God has instilled amazingly strong instincts in them, and they always seem to know what to do
No one has to teach them.
What breed is your doe?
