i have mixed chx. i know alot of people snob the chicken mutts but i love em. the eggs taste the same and they all look different. i guess that there is an advantage to having purebreds, you know that the eggs will be uniform and look good if you go to sell any. i was looking at what they had at hannibal farm and home the other day and nothing excited me. big chickens eat big meals and don't elude predators like a small fast bird.
