You are talking about the theory that they can either make meat or eggs but not both?
You are proving that one to be false. I have seen this with Pita Pintas too. The cockerels are big fast and the pullets\hens lay lots of big eggs.
The number of egg laid has to do with the ovaries producing eggs. That is a selected gene on it's own--does not link to meat production.
I've pondered that theory a lot and had concluded over a year ago that the "perfect chicken" was a myth. So, I keep a line of pure NNs, a line of egg layers (various and mixed breeds), and a line of meat birds (various and mixed breeds incorporating more NN blood), but what I've found is that some of my meatiest, heaviest girls are also some of my best egg layers and also give me some of the meatiest chicks for eating. Most of my NN girls have been weighing in around 7-8 lbs at one year of age, and give me large to jumbo sized eggs 5-6 days per week, even during the short days of winter without artificial light, the hottest days of summer, and through intense molting. Right now I'm just feeling exceptionally grateful for my good luck because I feel I currently have a lot of "perfect" chickens, but I also worry that my luck won't hold out. In the meantime my primary breeding focus will be on improving my meat line, and hoping I don't ruin any of them.
