How many eggs does a chicken lay per day? I am starting an allotment with my uncle. He claims that a vet has been giving him information about keeping chickens, but he's also a habitual liar. Anyway, I had read that chickens lay only one egg per day. My uncle says that one chicken can lay up to eight. Can anyone not only answer this question, but provide sources as proof so that I have evidence to show him? Thanks.
