I currently have Delawares, and I have the opportunity to get some young Cornish pullets. If I breed one of my Delaware roos with the Cornish hens, will they produce a decent sized meat bird? Or is this a cross that I would have to work with for several years to "perfect"? I'm not wanting some super ginormous 10lb dressed chicken out of it...just a nice 4-5lb dressed bird in say...8-10 weeks. Is this possible with this cross?
