I tend to think you're underpricing your eggs.
$3-$4 per dozen for 'natural, fresh' eggs is more the norm.
And $10/dozen for hatching eggs is not out of the question if you do your job as breeder.
As for selling started birds, you get feed at a good price, so that saves you.
A bird eats, on average, several ounces a day. As they age, it goes up. Over 22 weeks, you can expect them to eat about $6-$7 worth of feed each. You will have to sell grwon layers for $10.00 minimum to make a profit on the feed alone. This doesn't count other things like litter, water, energy, transportation, labor and so on.
My only concern is do you have:
A. Quality, pure-breed birds that will command premium prices?...
B. A market that wants to buy them?
As for cockerels, unless you can prove their worth as bloodline stock, it may be tough to find buyers. I'd look to the latino market, if you have one - and not ask too many questions of your buyers.
Overall, I'd say, yes, you could make a profit. But you need to price a bit higher on the grown birds - and do some research into what people want to buy and what they are willing to pay for it.
