This study assessed poultry farmers’ willingness in Ghana’s Western Region to use egg and snail shells as affordable calcium sources in poultry feed. Calcium is essential for strong eggshells and bird health, but traditional sources like oyster shells and limestone are costly. Using a multistage sampling method, data were collected from 284 poultry farmers through structured interviews. Descriptive statistics and regression analysis revealed that 80.28% of farmers were willing to use eggshells, while 65.49% favored snail shells. Education, farm size, access to loans, and extension services significantly influenced adoption. The findings demonstrate the potential of these alternatives to reduce feed costs by up to 20%, offering a sustainable and cost-effective solution.
