Great article! It's detailed yet concise and easy-to-follow. This would be a very good resource for anyone looking to build a small, moveable coop. What a lucky granddaughter you have!
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!
