Introducing a muscovy hen into a chicken flock?

[currythecockerel]

It's mostly size.

However, I do have a case here where a silkie rooster had an aversion to two cuckoo silkie hens I'd hatched and raised. I believe it was simply because they had different colored feathers than any of the others. He killed one and was in the process of killing the other before we caught him and put him down. No other chickens presented with this issue, just the one rooster.

Oh thats terrible I'm sorry! I've never realised roosters could go as far as that, some of them can definitely be horrors
