Well with her being that young and it being her first litter i wouldn't expect to much from her when Tracy had 7 nethies in a litter that was an amazing size litter, mine range from 1 to 4 but not all survive normally due to the dwarfing gene i suppose, and 1st litters tend to be smaller from what people have told me.
You can kepp mother and daughter together if they get on well enough, but sometimes mum gets fed up with them it depends on the doe i suppose.
I would pay close attention to her when she is due to go into labour if she is straining for along time then it can be a sign of a stuck kit and sometimes the kits can be quite big for the mum, as in if she just has 1 or 2 babies they will be a lot bigger than 3 or 4,
Do you have an idea on how many days pregnant she is? You need to count 31 days after to get the due date, expect her to make a nest before, if it is her first time (and i have a couple that do this) they can start making there nest quite early as in the 2nd week of pregnancy and i have seen 1 of my does pull some fur then too but usually they just start moving hay about and getting an idea of a nest, and then build it properly the week they are due.
Don't forget to give her some banana the week she is due to boost her potassium levels and 1/2 a rennie's for the 3 days before kindling for hercalcium levels, also might be worth giving her some raspberry leaves.
Don't stress out if she doesn't eat very much or anything a day or two before she is due, they tend to do this, sometimes they will just munch some hay and i always give my pregnant does the Burgess super forage as they seem to prefer this.
Just some tips to get you started lol PM me if you need me but there are a lot of folk on here with more knowledge than me
Edit to add: does can go anywher up to 35 days i have only had this happen once,
