Food to egg ratio?

[newchickens2009]

(I had posted this already and someone told me that I put it in the wrong place and that I should post it here).
What I am interested in is the food to egg ratio for my layers (r.i.r., leghorns and sex-links) so that I may determine the price for sell eggs.
Any info will be greatly appreciated!

Per day, per layer, while laying, 1/4 lb of layer feed for lightweight breeds or 1/3 lb of layer feed for heavyweight breeds.

Free range or other foods added will change this, but that's a good place to start.

There is a free spreadsheet on the forum posted by raizin. You can enter the amount of feed, number of hens, and keep track of the number of eggs layed. The spreadsheet will automatically calculate the cost of feed per egg for you.

I dont know about feed to egg ratio but here in Portland oregon eggs sell for $4.00 a dozen.
