Cornish Cross are one of the worst breeds I have seen in my life, if not the top worst. The only thing they do all day is sit in their poop and continually eat, only occasionally roaming around the yard even though there is plenty of space for them to do so. Not to mention that their poop is literally everywhere you step and it is in huge piles, much larger than a normal chicken's. They are destructive and turn everything to a pile of poop and mud. Cornish Cross are oriented so much to food that they attack you for it. This goes for both genders; the cockerel started attacking me first when he saw me with the feed bucket, and the pullets followed along and attacked me as well. Two of them died before butcher age, one from leg problems and the other one from a heart attack. Cornish Cross are extremely loud and they constantly make this annoying honking noise because they choke on their food since they eat so fast and so much. The only things good about this crossbreed is that they are fast choice for meat production and they can easily fight off diseases such as coccidiosis and fowl pox, but other than that, don't waste your time and your yard space. American Bresse would be much better.
