I have exhibition Orps and closer to production Orps. I noticed the production quality crew, is a take no crud from anyone types. They tend to be the ones who end it. The bigger exhibition boys are cream puffs. If you are getting younger birds, introduce them at nite. The next day, there will be a show of dominance by the bigger birds. But, they will get over it and go back to eating. As punishment for tail feather eaters, I put them in a pen with bigger birds. And they do get their butts kicked. So, you will have to keep an eye out for a few hours. The bigger birds can tare open a smaller bird.
And just to prove we can ALL get along, I have a coop for bachelors, with about 8 cockerels and one Roo. ALL GET ALONG. After the initiation period. Every new boy who goes in usually makes it out okay. And I have a Birchen Marans cockerel, an Australorp Roo ( he runs the place ), 2 Golden Comet cockerels who look like Red RIR's with white legs ( anyone want one? lol ), a RIR cockerel, a Black/Buff Orp mix, a huge Black Orp with TOO LITE an eye ( I just like him that is why he is alive ). Plus a Wyandot or two. All live together. And they have some room. So we're all one happy bachelor pad. And if they can make it together. You should be okay. lolol
