You can offer them Oyster Shells in a separate container at 16 weeks. They will consume it if they need it.Would it be okay to put oyster shell in after the first egg, or do they need it before they start laying to get enough calcium?
Also offer them Granite Grit, separate from the Oyster Shells, if you don't already provide it. GC
