I also keep my silkies seperate from my LF in a 4 foot fenced in area with a seperate coop (I built out of a big dog house). I have a PBR, BO and RIR in that "pecking" order. My Rocky is very bossy and will peck her sisters to keep them in line -but has never drawn blood. Then I have 3 pullets...2 EE's and a Welsummer that fly INTO the silkie enclosure to get away from the LF. These 3 pullets also eat from the silkies feeders and waterers, but have never been aggressive toward the silkies. I watch them closely and will take action against them if they hurt the silkies. They would rather have their feet pecked by the silkies than risk intimidation by the LF girls. They realized a long time ago that the silkies have bad aim and don't peck very hard.what kind of layers do you all have that get along with silkies?? I'm sick of the Wyandottes in particular, they are just down right mean to everyone except themselves and the rocks. The rocks are a little better, but not by a whole lot. I've contemplated getting rid of these and getting a layer that is more gentle with other breeds, especially with cresteds, because I don't want to separate out my Polish. I have far more Polish than layers. BUT-- I like the color of the brown eggs, so I still want brown egg layers... I read how everyone else has layers that get along with their birds and that is not happening here... at ALL. Sigh.
I hope you can get your Wyandottes under control.
