I guess my question with your plan is what will you do with hens once they get older and stop laying with regular frequency? Are you still willing to feed hundreds of older birds that are no longer contributing regularly? If not, what is the plan to get rid of those birds, as you won't be eating them (and I assume don't want to see them get eaten either).
As far as price per dozen, I can't answer that as I don't know what prices are like in your area. In my area eggs can go for almost $10 a dozen, but that's definitely not the norm in most areas of the country.
