One of my young does delivered last night to her first litter. She had six healthy looking babies but did not build a very good nest. The babies were dead when I checked on her, all were laying out in the open. She was still pulling fur today. Is this going to be a problem doe or just try it again? Is there something I can do to help her? I had wood chips and straw in the nest box and was giving her more straw to build her nest with. Thanks.
