30-32 days for normal pregnancy. If shes already pulling fur that's a very good sign that everything is in order I would just keep an eye on her over the next few days. Personally I socialize with my Does quite a bit pregnant or not so that it is a regular thing and once the babies arrive you have less chance of them getting cranky and cage aggressive I touch the kindling box quite a bit as well so my scent is on it and offer some fresh herbs such as cilantro while doing so. If she hasnt had them by day 33 schedule a vet visit as there may be issues but right now I would just go about business as usual with your buns. Rolled oats and black oil sunflower seeds (about a quarter cup of a half and half ratio of them per day in addition to regular foods) will help to sort out milk production especially as some Moms have issues starting up. Some raspberries, especially the leaves of the plant (well washed) will be a treat and help to ensure that there are no uterine issues for your doe. Also the above all best thing for rabbits in nearly any scenario is fresh dandelion any part of the plant will help with a myriad of problems from milk production to G.I. issues. Some grocery stores are selling it in the produce section and if all else fails you can always try to gather some from outside; wash well, they can eat the flowers as well as the leaves and you can make a tea with the roots and add that to their water. Make sure to rub the Does belly, as well if you have problems with that, gently as she will be sensitive. Good luck to you!
