After a bad hatching, i have just two chicks - 3 day old chocolate orpintons. I want to introduce more chicks - 3 more - to raise them and then keep. A guy local to me is selling chicks the same age, but they are Silver laced wyndottes and are large fowl. I have read a load of posts about mixing them but not really any wiser. Will these breeds get on? Can i introduce them during brooding period? Thanks!
