RoostersAreAwesome, I love that you have one named Lupin! All of my silkies are named after Harry Potter characters except one.
I have Snape, Neville, Buckbeak, and Fang as roosters (or cockerels, since they are not old enough to be roosters yet, as I just learned!). Dumbledora, Harry, Dobby, although male in the books, are some of my silkie pullets. I named them before I knew their sexes. I also have Poppy, Tonks, McGonagall, Ginny, Hermione, and Luna for silkie pullets. And Kimberly, the sole one who is named not for a HP character, but for the friend who got me 7 more in February after I lost 4 to a predator.
Poor Sirius, Ron, and Peeves were killed by a hawk in January. I also lost Buffy (the one silkie at the time not named after a HP character, but after Buffy the Vampire Slayer). Buffy was my favorite silkie of all time. I was so upset to lose them all. I almost lost Poppy and Dumbledora, but Mom interrupted the hawk and chased him off. As near as we can figure out, the hawk divebombed the bird netting that was over the top of the run and broke through. So now all the runs are covered with chicken wire across the top. They only free range when I'm outside with them. We have a lot of predators in my area. Hawks, as mentioned, and coyotes and bobcats, too. A friend lost some of hers to a mink!
