Microsoft founder Bill Gates has launched a campaign to help extremely poor families in sub-Saharan Africa to raise chickens.
The billionaire says raising and selling the birds can be efficient in tackling extreme poverty.
He has promised to donate 100,000 chickens, and the project's page has already been shared thousands of times.
The UN estimates that 41% of people in sub-Saharan Africa live in extreme poverty.
Mr Gates said a farmer breeding five hens could earn more than $1,000 (£690) a year. The poverty line is about $700 (£484).
He added that the goal was to help 30% of the rural families in sub-Saharan Africa raise improved breeds of vaccinated chickens, up from the current 5%.
