Suebee, with any luck maybe the hawks think your Silkies are tribbles instead of chickens?! (Star Trek "Trouble with Tribbles" episode). It's said that hawks don't eat tribbles.
(seriously for a sec, I'm really glad they've left your little feathered friends alone!)
And Spotted, yikes, trouble in your midst. Poor squirrel. Interesting that Obelisk and Penny were not daunted. Who is Mr. Rumpled and are these your feather babies too? So sorry one got taken.
There is a purple martin bird house high on a pole very near the hawk nest in my yard. Squirrels always set up shop in there instead of birds and right now there is at least one adorable baby squirrel being raised in there. He popped his head out tonight to watch BJ, Annie and I and I cringed because the hawk pair fly back and forth right past that bird house and I hope the poor little guy doesn't get taken. Normally the squirrel babies play and play up on top of that bird house (and sleep inside it at night) until they are old enough for their mom to teach them how to get down the pole. This little guy is not going to be safe doing that.
Speaking of my hawks. I'm noticing something new now. I think the red-tailed hawks I saw might have just been flying over a lot, right in the area of the nest. But the pair definitely going to and from the nest seem like they might be another kind of hawk - I'm guessing Cooper's but trying to get a better ID this weekend when I can hopefully be around during better light. If Cooper's, I'm not sure how risky for the chickens. BJ roo scolds the sky when he sees them but he doesn't get totally bent out of shape like I would expect him to. He goes back to doing whatever he was doing, which is usually following hen Annie's every twist, turn and whim.

According to a Cornell University fact sheet:
Cooper's: 15-20 inches long, 8.83-21.07 ounces
Red-tailed: 18-26 inches long, 24.36-51.54 ounces
Both are described as eating medium sized birds.
