I have a 1.3 group that I picked up in July and they had their first litter of babies in late October and last litter about 6ish weeks ago. Each female has had one litter ranging in size from 8-12 pups. I have them in a 10 gallon glass tank and feed a mix of Mazuri, bird seed, occasional veggies, & sometimes dry cat food (this was recommended for added protein to me after a newborn pup was eaten, I had no more pups eaten after I added it). They are kept indoors and are on aspen that I change every 5-8 days and I clean the pee corner once between cleanings. I do have 2 females from their last litter in the tank as well, I plan to move them to a rat breeder cage once I get another male (I had mistakenly fed off the male and have one on order).

They are good parents, the male is huge, & have a fairly decent disposition. Is this normal to have a production pause like this after 1st litters? Or is it normal for my male to become disinterested in the females? None of the females look pregnant at all.

I feed these guys to my 2.6 balls, all of which are 2012 bps, except for a 3 year old mouser, who is not interested in ASFs at all.

I also have a trio of mice that are producing perfectly.

I posted this question on another forum and had one reply to feed them off. I really don't want to start over, but I will if I need to. I'm hoping there's something obvious to one of the group members that I'm doing wrong. Maybe I could play them some Barry White.

Any suggestions?
