For me rats have always been easier. but a healthy 6 week old rat would be about as large as you could feed off.
Baby corns of course could ot eat any rat. but a well fed corn from birth might be able to go on pinky rats 1 day old at 3-5 months old.
As far as nutrition, I do not see a big difference? If I had to pick the best on a guess it would be a gerbil, they tend to stay leaner since they are hyper. DO NOT breed gerbils for feed as snakes get hooked on them. I know many people with ball pythons and that is all they will eat.
But most people like mice for corns. Maybe becasue they start on mice? Most of my corns are not picky, if it drops in the cage they eat it. But it comes down to whay you are comfatable with. 2 cages of 1.4 rats would/should/could produce a LOT of rats from 1day to 4-5 weeks old to freeze. Then maybe a few mouse case cages for the young stuff?
I sell 500-800 mice a week and 200 rats so I have it easy, I just pick what I need. But our breeders have mostly quit this year.. So it looks like I may have to do it again.
Speaking of which, I'm off to town, I live 60 miles from my work, and I need to leave. I stay a few days in town usually to save on gas, so I'm not igoring posts, just away.
It will be interesting to see feedback on feeding rats to corn when I get back. I don't think I've ever seen it talked about?
good luck
Big Tom
