There’s a link on the page above to the Learning Centre - it’s a great resource. If you have a specific topic in mind, just type it in the search box - there's a wealth of information on past and present threads.
You can have any number of chickens and still get some eggs, as long as they are hens. If you want 6 eggs a day then you should get 6 chickens. Although, this would change depending on the breed you want. Some breeds lay 7 eggs a week, some lay 6 a week, some even lay just 3 or 4 a week.
1 will get you eggs but not many. The average number of chickens is one per household member but check your locations zoning if needed. I have 11 chicks myself. And only 5 people in my house.
