I cull every female that eats babies, first litter...tenth litter...it doesn't matter to me.
I also handle pinks and haven't ever had the mother reject them.
You're much better off culling heavily in the beginning. It takes longer to get the stock you want up and running, but when you do you will really have something then.
These are the guidelines that I use to pick breeding stock.
- They must come from a litter of at least 12 pups.
- They must conform to whatever trait I am trying to breed for.
There are the guidelines that I use for culling animals.
- Biters are terminated immediately and their young are disqualified as breeding stock.
- Tub chewers are terminated immediately and their whole tub is also wiped out.
- Baby eaters are terminated immediately.
This sucks at first, but now I have a colony full of rats that produce 12+ babies per litter, don't bite me, and don't chew through their tubs.
