Snap has developed a very bad habit. When she finds a setting hen (chicken hen) and she can easily access her, she will take every opportunity to sit and stare at the hen, terrorizing her til she flies off the nest. Then she eats the developing eggs.
Just recently she did this to my sweet old Silkie hen Izzy Lou, and ate all of her six eggs. She seems to do this most to hens that look "funny"..different from the others...the Silkie, and she always terrrorizes our Ameracauna hen whenever she can. It took me a while to figure out what is going on. It seems that she has learned that she is not supposed to do this, because she will no longer do it when I'm anywhere near, because I chase her away, of course. And I've see her run away a couple of times as I've approached from a distance, which is kind of funny, actually, she's like a naughty child.
It's not a huge big deal, because we are about full up anyway, with chickens, but I was hoping that Izzy Lou would have some more babies, she's the best mama we have, and I feel sorry for her that she lost all hers.. Short of confining Snap, or getting rid of her, or moving the broody to a safer place, which are obvious solutions, I wonder if it's possible to discourage Snap from doing this by putting some eggs in Izzy Lou's now-empty nest, that would taste bad, or maybe just fake eggs? What could I use that would taste bad to her, but still be safe?
