Gin, I hope you aren't feeding whole corn to the rats. Dried corn can contain a mold which carries aflatoxins, which can kill your rats over time. Especially with the weather we've been having lately(no rain), the mold count has been exceptionally high and whole fields of corn can't be used because of it.

Being "corn-fed" doesn't make a rat, cow or horse better. It makes their muscles turn yellow and they get fat and unhealthy.

It would do them ALOT better to just feed the lab blocks and some of the mix I wrote about. Tri-colored pasta, oatmeal, cheerios, chex, off-brand total, dried split peas, dried lentils, puffed wheat, puffed rice, dry brown rice, granola, etc. is a much better diet and cheaper for you.

I know I wouldn't want my snakes eating an animal that was fed only corn and corn-based lab blocks. Not too healthy in my vet tech's eye as I've seen what it can do to an animal.
