Are there any heritage breeds that are well suited to being meat birds? I am not interested in 'Crosses'... i want something that i can breed myself. Also, can Dark Cornish chickens reproduce naturally? http://www.mcmurrayhatchery.com/dark_cornish.html <- (these ones) I heard some where that Delawares and White Rocks where good meat birds... any personal experiences to back this up? If you know any birds that you have used for meat that are non crosses please let me know!
