Remember that this is a forum who keep chickens as pets, and just want to offset part of the cost of their hobby.
Therefore, the vast majority of them are selling eggs for a significant loss.
When you try to figure out what you should charge, you need to figure in...
Cost of the birds to purchase, and cost to raise to laying age
Housing costs
Bedding, waterers and cost of feeders
feeding the birds
Losses of birds
Egg carton costs
Marketing, including webpages, etc.
YOUR LABOR - VERY significant
Cost of replacement birds for poor layers,those lost to predators, etc.
Predator control - such as lights, electric netting, fence charger, livestock guardian dog, feed, vet costs, etc.
Other costs, such as tarps for shelters, repairs, etc.
Medications
Vet bills
Costs of bird fanciers membership, and so it continues....
PLUS remember that you have to feed/house/tend your birds in winter when their output is insignificant, and not nearly enough to even cover their food bill!
I have a large flock, and therefore cannot afford to charge what the majority of the people on this list charge, as I have to make a profit.
Therefore, I do not sell to my neighbors who buy from hobby people who keep their birds in cages and tiny pens. Instead, I sell to high class restaurants who want to support truly humane farming, and are willing to pay for it, and at farmer's markets where they are willing to support farmers.
Please note, that I realize that most hobby chicken owners raise their chickens well - just not in my neck of the woods.
