yeah. The pinkies are under the hoppers and I havent had any loss due to suffocation.They always nurse under a half log hide,The moms always remove most of the aspen from inside the hide so most of the babies are on the glass.Ive even seen the babies under dad as well??? not sure what thats about.At times with 20 babies on the ground, Ive looked into the tank and see nobody. I look under the log hide and all 20 babies are under 2 moms and dad. Not sure whats happening in your case. what is your setup ?
