I recently aquired 20 CH females. Since I got them I have attempted feeding twice. So far only about 8-12 of them have taken the live rat pups I've offered. My question is, when should I start force feeding the ones that haven't eaten? I have read Adam's guide many times. I really do not want to resort to mice, I just don't want the headache of dealing with rats AND mice. Also, at the moment I do not have access to any ASFs. I just want all these girls on rats. Any advice?
