So my ASF breeding has been going on for about 2.5 months. After a slow start I now have them producing regularly. The downside is how slowly they grow. I have 4 groups of 1.3 and 1 group of 1.5 . I have a tub full of weans that seems to be the same size week after week. The upside is that they have worked to get some picky feeders going again. It's still a work in progress but at this point I can't say that they could ever replace rats for me.
