If you don't know the due date for your doe, how can you tell if she will deliver
soon?  There are two body conditions that are easy to identify.  Your doe's
udder will suddenly swell and the shape of her hips will change.  Some does will
deliver immediately after these changes occur, some does like to fuss around,
pacing and pawing at the ground for hours.  When you can see the "triangle"
you know the kids are in position, she is quite uncomfortable, and it's only a
matter of time.  Here are a couple pictures so you can see what I'm referring to.

doe hours before kidding
doe hours before freshening
This is a picture of Cora, four years old, about to
have quadruplets.  These photos were taken
hours before she went into labor.  See how it
looks like the spine is coming off from her rump
- like the tail head has been pulled up?  She is
"loose" like that all the way up to her hips.  Many
does don't separate quite this drastically, but
like I said, she was about to have quads.  This
picture also shows the "triangle" below the
rump.  Most does look "sunken" when they get
close to freshening.  However, this triangle is
most distinct shortly before they go into labor.
Here is another angle.  Can you see from this
photo how low to the ground her belly is?  
The babies have "dropped" into position and
are merely waiting for their turns to be
delivered.
 This angle doesn't show the
loosened tail head quite so well, but you can
see the "triangle" and you can also see that
she looks incredibly "skinny".  This had also
happened overnight.  One day she looked
l
ike a submarine on sticks (she was 195 lbs)
and the next day she looked emaciated!
If you are anything like me, I like to be around when the kids are born.  I try to
carefully note when every doe is bred.  I also like to take notes on how each doe's
delivery happened.  Every doe is different.  If a doe delivers early (as did Cora in
this case), or if I forget to write down a breeding date; then, with the help of my
notes, I can usually know pretty close to the day when she will be having her kids.
I remember one day I was cleaning out a stall, getting
it ready for one of my does that would deliver soon.  I
looked up and saw her with this look on her face, and
thought, "Uh, oh, I must have written down the wrong
due date."  Sure enough she had kids within a couple
hours.  When the kids start moving into position and
the doe has mini-contractions, the doe will stand and
stare at nothing - as if looking inside herself.  
Sometimes she even will "talk" quietly to the kids
while doing this.

If you see a goat doing this with the head lower and
looking down the goat is probably sick.  It most likely
has a fever.  If the goat also presses it's head against
the wall it has a headache and probably needs
thiamine treatments.  Watch the goat closely and call
your vet with your concerns.
