I have a grow up tub and in the last batch of little ones I moved over 1 was found dead not I am wondering in your grow out tubs how far apart are the generations? I have 2 trio's going with one of the just starting. The older trio are throwing 8-12 pinkie per female the younger trio has thrown 4-6 pinks with one female giving me 1 litter so far and the other giving me 2 litters. Also how long to you leave the weanlings in with the parents before putting them in the grow out tub?
