If I go backward 14 days from your statement in the first post of trying for two weeks, and then count forward, this nest material gathering is right on schedule for a kindling within the next few days (assuming the pregnancy occurred at the first attempt). Whether she is actually pregnant or doing a false pregnancy, we can't say from here. Normally, does don't start gathering material until a few days before the babies are due, but until you have some experience with a particular doe, you can't be sure just what she will do.
