I am intrigued by this breed and am thinking of adding to my flock. My question is--am I able to add this breed in with my other birds? Is it best to just have Silkies or can they "mix" with birds of other breeds? I currently have RIR, Golden Sebright, Rhodebar, and Swedish Flower. I prefer to have a variety as opposed to a single breed but will only mix-up birds who seem to get along ok. Any insight is helpful. Thank you.
