I have a Production Red that we've allowed to breed with our hens last year. We ended up with a bunch of cockerels but I was surprised to see the Barred Rock cross get so much larger than his father. Is this typical of Barred Rocks vs. Production Reds? The Brahma cross ended up much larger as well but I understand Brahmas are typically bigger birds. Is my Production Red a runt or are they usually smaller than Barred Rocks? If they're typically bigger is there way to make sure the next one I get will end up larger? I kind of like the idea of a rooster that can push my dogs around if need be. If I bought from a smaller breeder could they ensure good genetics and size? Does anyone know of a breeder in the Central Texas area that breeds Rhode Islands? Heritage would be even better but probably very unlikely.
