As above. I've had 3 Jill's rear one litter in the past. The actual mother was in fantastic nik throughout the rearing, never lost any condition. It was a large litter and all did very well.
It was a mother and her 2 daughter's that raised the litter. All 3 mated around same time, the daughters by a Vosectomised hob, which obviously had phantom pregnancies.
