Honestly, there is NO WAY to look at those 2 pics and have even a guessable time... but I would say that she is still a ways off... maybe 1/2 way through the preg???? Do you have any idea of when she could have been exposed so have some sort of a date to work off of??? You say you have no idea when she could have gotten preg or how far along... so can you find out WHEN the male was in there and when he was out???? Something to start with????
I am not a goat person, per se.... BUT, I have seen pictures of some that are wider than they are long and still go weeks before giving birth.... and I did some farm sitting for a friend with goats and some of them could not barely waddle... others would not look very far and pop out a baby....
