I was just reading that the Egyptian Fayoumi is the fastest maturing chicken, with some cockerels reportedly crowing as early as 4 weeks and hens commonly laying at 4.5 months. Of course, the Fayoumi is a very small breed, but it got me thinking...does the rate of maturity have any relation to growth-rate? Really, wouldn't we want fast growing, but slow MATURING chickens for meaties? Cockerels that aren't going to be crowing and fighting at 5-6 weeks, like the Fayoumi. Or does that maturity rate have a lot to do with the filling out that, for example, my Delaware and Chantecler cockerels are lacking at 16 weeks? If that's the case, I'm trying a Cornish x with a Fayoumi. But really, what are the fastest growing LF breeds, even if they aren't commonly known for being good meat breeds. Leghorns? BR? RIR?
