a hybrid chicken would probably lay 5 eggs a week maximum but they will go off lay during the moult so production would fall, and you would need to replace them at 18m-2yr. to get 10 eggs a week- might need 3-4,
to get 2 dozen reliably 10 hens?
i hardly eat eggs and tend to sell the excess to pay for feed.
perhaps work out how much space you have, and wether you could sell the excess then decide on the number to get.
