Very well written. I would also mention that high production birds tend to peter out after two years, where as heritage birds can be consistent for many years.
Nicely done. The author makes an important point in averaging eggs per week according to breed. Production breeds, as mentioned, may produce more than average in spring.
To the space section consider adding that one nest box to three- four hens is a good rule of thumb.
well done.
A very concise, well-written primer on the subject matter. I would add that climate, molting, and the birds' ages should be factors to consider as well. Chickens' production can be affected by temperature, daylight (or lack thereof), the stress of molting, and aging. As an example: we have 6 one-year-old birds, who give us more than enough eggs at the moment since they're in their prime. Once molting, winter, and aging hits, we'll likely see fewer.
All said, I still say everyone thinking of keeping chickens for eggs should read this!
