What feed do you raise?
I never bought oyster shells, I used to feed ground up chicken shells back to the chickens.

Corn, Sweet Corn, Wheat, Barley - and this year some hulless oats. They get grass and all the culls and excess from the garden too. I buy soybean meal for protein supplement and a trace mineral mix.
Crushed Oyster Shell is common here - actually many driveways are paved with them... I run my egg shells through my Victoria mill and feed them too.

(had to chuckle on the ‘chicken shells’) Gotta give them the calcium for new egg shells...
