Hi,
I have two buff orps (I love them, they are so sweet) and I have them separated right now with four others (Silkie/Polish/Black Australorp/EE? mixes) that they grew up with. I have a question mark after the breeds as this is what I was told but I have no personal knowledge of their background.
I had these chicks together as they were still on grower food and my other chickens are on regular laying pellets. But I am going to try to blend them in with some of my other chickens come spring and I have thought about this a lot.
I feel I can put them together with my Silkies, my only "Sizzle", my Polish hen and my Cochin bantams without any major problems. I am going to try it but keep a close eye on them because I would never want them to get hurt.
I hope it works. Good luck! Genie
