I have been breeding rats for a few years now and thought I would get into breeding ASF's. I feed all my rodents Mazuri 6F and keep them on dried pine without any problems. I bought a 1.3 group of asf's from a breeder and have been raising them up for the past couple of months. Just this morning one of my asf dropped her first litter of 9 and all seemed well, I just peaked on them and noticed half of the babies were dead, the mother was still on top of the babies including the dead ones. Is this something I should be worried about being her first litter?
Any advice would be greatly appreciated.
