I dont have too much problems with my ASF. I like them for the large litter size. They are slower growers but for picky balls they usually do the trick.
They can be jumpy. I personally still clean them twice a week with my other rodents. because they are in the house and the smell of them does bother me. I think Id die if I went three weeks.
I havent had a problem with them ruining things like water bottles or chewing out of their cages. Typically my breeders I keep for about a year. I have had lots of fun breeding them. Working with different color, pattern. and my pink eyes
