We have a doe that had a single fawn on our property about May 17. We saw the fawn maybe two or three times but not within the last 6 days. How long would it take for the doe's milk bag to dry up if something has happened to the fawn? We thought that maybe having one fawn the milk bag does not always appear really full, or that maybe when she is done feeding the sack will look smaller. We'd appreciate any info in this area anyone could give.
