2 Buff Orps and 2 Barred Rocks. One of the Barred may be a cockerel, we aren't positive. Many people post about separation, keeping the little ones away from the big mature ones. I have found the exact opposite. Just to see what would happen I put these 4 in the run with the 9-10lb Australorp and a 2-3lb bantam... some type of game chicken. This has been the most comical thing I've ever seen. The 2 old ladies, 3 years give or take are terrified of the babies. They hide on one side of the run under a pallet that is leaning on the wall of the run. They poke their heads out now and again but mostly stay there. When they are thirsty or eat they come out, the babies run away... soon as they are done, back under the pallet. The babies have almost total run of the place. It's hilarious I find. I'm fixing to go get 2-3 more 4 week olds from the same place. As my meat plans have fallen through due to my inability to make the kill I'm going for eggs. I'm still trying to get these little ones comfortable around me. Will post pics when I can. Absolutely adorable right now though. *Edit* I know now why I don't have it in me to kill them, nor will I. When they are young they are comical cute little things. Knowing that, how can I take its head off or slice its neck when the time comes. I will make do with eggs!
