I think the question is too broad. I would have an opinion per breed.
For example all of the American breeds are dual purpose birds. None are purely meat birds. We have general dual purpose birds, dual purpose birds that emphasize the production of poultry meat, and dual purpose birds that were bred to emphasize the production of eggs. The NH and Delaware were intentionally developed to emphasize the production of poultry meat. Therefore, my expectations for these two breeds would be higher than for some others. Some like the Buckeye have a conformation that is better suited for the carcass than it is for egg laying capacity. Jersey Giants were meant to be good and large capons. Dominiques were more by chance originally, more refined later. The emphasis for Reds was more on the production of eggs. Their long backs, and deep bodies (brick shape) equipped them to be good layers.
I believe that it is important to consider that before the mass movement to the cities, industrialization, and the specialization of the production of poultry products; meat was a by product of egg production. Dual purpose meant hens that were salvageable, and extra cockerels had some value.
The first chicken of tomorrow contest featured the NH winning. The second year it was a NH x Cornish. Cross breeds, outside of the small family farm, dominated the production of poultry meat. Even early on. The NH x Rock was a common cross.
I do not think that it is helpful to evaluate a pullet by per week or month numbers. It seams more effective to judge her by her pullet year. That is from point of lay up until she molts in her second year. Then when she molts, and how long it takes her to molt is a big deal to me.
If I had my ideal NH she would lay 200 larger than large eggs in her puller year, and the color would be a rich brown. The flock's eggs would be uniform and of good quality. She would come into lay around 20 wks, molt late in the season, and molt out in 8wks.
He would be a meaty fryer by 14 wks. weighing 3.5-4lbs dressed and ready for the pot. He would be a broiler with good weight by 18-20wks.
If you've already answered this previously then I apologize for asking again, but do you trap nest?
