i got my first asf's about 4 months ago. i just got 1.2 to start off with. both females were both of breeding size and one was prego when i got them. the male was only about 25g's though.
well the one female had her first litter a few weeks later and only had 4 babies. one died and i was down to three.
i now have 2.4 rats and have yet to have another litter or any signs of my females being pregnant. the babies are all now around 40grams, and the original male i got is now up to par with the other females at 55-60grams.
so just want some advice. maybe im just being impatient, but i figured i would have a good colony going by now.
