We were just as scared the first time we had a pregnant goat due to give birth. I wish you luck! And, if this helps you at all, the actual birth part was fine. She gave birth without any help, but she did appreciate us being with her (however, it's different for every goat!)
When do you seperate the kids for the night?
Since we haven't started milking our does yet, only once they will be rehomed and taken away from their moms in a couple of weeks.
How do you do that? We'll probably do it for the first time tonight, but we have a divider in the barn so that the whether-ling can sleep on one side with some does other than his mom.
What time? We usually put the goats to bed when it gets dark, and we'll separate them when we put them to bed.
Do you need to feed them at night? Nope.
How much milk will a first freshener give daily? Depends on the doe.
Whats your milking routine? Sorry, but I can't help with that. Never done it before.
Milking supplies? We have a milking stand and we'll milk her by hand.
Alternatives to commercial feeds that help your doe keep her weight and milk production up? We don't usually do anything except during the pregnancy, but grain and black oil sunflower seeds while pregnant.
Again, I wish you luck!
