If I may, I'll toss my usual wet blanket here.
I would suggest you be wary of egg production numbers. They are not cast in stone as there are far too many variables to accurately say what one or the other will do. Egg laying is still seaonal for most of us unless we want to resort to controlled and confined housing.
RIR's and A-lorps have been bred for over a century to produce eggs. The Delaware was not - it was a broiler first, as I understand it. WHen going with a breed like the RIR's, A-lorp or the production hybrid, the 180 eggs per year number is closer to the truth of the matter for the most of us.
Sure, someone always chimes in with how many eggs THEIR birds gets, but that's them. That can be misleading. Yeah, you get plenny eggs in spring, but what about the summer slowdown? The winter halt? The molt? The stoppage because the coyotes have been nosing around or the lawnmower got too close?
As a newbie (and recall, the OP is a self professed newb), I would plan on an egg every other day and less outside the peak seasons. If you get more, hey, great! If not there wont be any great surprises.
