I have had no problems with my Silkies, other than that they are so frequently broody - lol! I've had them for over 2 years, and my flock has only had mites once in all the years I've had chickens. Don't let that deter you! I love them so much, and they aren't picked on (another thing I've heard about them). And they are the best mamas! My Violet has raised multiple fosters.Aww I saw a picture of a Spitzhauben and the top feathers look a lot like polish chickens feather I wonder if they're related. I do want Silkies but I heard that they are more susceptible to lice and mites so I may not get them.
