I have three does in a colony who all had litters within two weeks of each other. One of the does (Kiwi) didn't build a very good nest so I borrowed some hair from another does (Alice) nest to make up the difference.
Because the borrowed hair had the scent of the Alice on it, Alice thought that Kiwi's nest was hers and defended it as her own.
One evening when Kiwi snuck into her nest, Alice came in and there was a scuffle inside the nest box. One baby was killed, and one suffered a broken back and is not pulling itself around on it's front paws. One broke it's leg.
Lesson learned... Do not borrow hair for another does nest.
