I don't know how the egg bribery stuff ever works in the US. Eggs are cheap here in the UK. You can get half a dozen eggs for under £2.
It probably costs people more in time and travel to come to the allotment or meet up with C to get an assortment of eggs that won't taste any different to the pasture raised eggs they can buy from a shop.
One can hardly advertise the eggs as free range without telling the same lies as the large egg producers.
The only attraction one is left with is tryinng to persuade people that the hens are in better keeping conditions than the batteries.
This isn't necessarily true now in the UK. In fact, many of the pasture raised egg concerns can provide far better keeping condtions than many of the backyard keepers.
