Wrangling Critters

I have found 2 issues. 3rd Glossy Drecklett not being moved from the incubator. Even when I remove it and wrangle it the Dupes will not put it in with the other Glossys.  Also, I set up an overflow room for Hatches(auto-wrangling after 8). Instead of moving the excess into the next room, my rancher starts wrangling them ALL. Another Dupe comes in, moves them into the next room and then the rancher also comes in and wranglers them too. I'm positive I have all the drop-off pieces set correctly.
