40 day old rats aren't large by my standards.. they've only been weaned for about 10 days at that age. I call them medium at 2-3 months. Large 4-6. But maybe I just have slow growers, I don't know...
I am not much of a rat person, so I just used the avg. days that RodentPro provided for their sizes for a timeline....

....I had my schedule and production worked out perfect with my mice.

....but now I deal with all frozen, too many mouths to feed, and too little of an apartment to be breeding mice
