In my experience (NDG), first timers are more likely to need birthing assistance. Luckily, I have never had a tangled kid, but I have had to pull many of the first borne babies out -- kid #2 usually follows without assistance. First timers also tend to be noisier -- loud Baaing -- so you are alerted when the babies are on their way. Now that my does are at least on their 3rd year breeding, the babies pop out. We attend to dry and warm the babies, since Mamma is too busy birthing #2 to lick #1. We also help the babies find the teats for their first nursing. I also give a product called "Nursemate Lamb ASAP". I my opinion, it helps the weaker kids through the birth stress and gives them some calories until they can get nursing well.
We use 4 ft chain link gate panels to set up temporary birthing pens in our garage. We place down tarps and then cover with straw. I tie dollar store laundry baskets to the panels to make hay feeders. My husband makes wooden baby boxes so the babies have a warm snuggly place to sleep. Add a bucket of water and you have a birthing pen. We generally keep mother and babies in the pen for a week. Then we disbud the babies, and momma and babies go outside to the buck pen, since Papa is with the still pregnant does. When the buck pen gets too crowded, the bucks go back in their pen and the mommas and babies go in the larger goat pasture. The 4 foot panels get reconfigured out in the pasture as a creep feeder for the babies. We get the older babies used to eating grain in the creep feeder. This helps us corral the babies when it is time to sell.
Remember, you will to clean your birthing pen of wet soiled straw. Does your basement have a exterior door? I would hate to have to drag wet straw through my house (although I would do it if need be). The garage is an easy clean out.
