Now with that in mind, how many chickens and roosters would be needed to maintain a 20 year breeding program? Say for a family of 6 to 8 people to have fresh eggs daily and fried chicken once in a while. Here comes an eye opener VenomJockey.
Well, we eat a whole chicken weekly so we raise 55 birds a year for that. If your hatching eggs and not buying meat birds that will cut into your egg production.
For eggs we keep a dozen layers that barely keep up some times. I'd say if you could have 3-4 completely separate flocks you may be able to swap roosters around enough to not have problems.
