I had two Cochin Bantams until one pecked the other to death, booo. My favorite of the pair, too. Booo again.
You cannot punish a chicken.
I'm considering getting some chickens that are 'free range' chickens, there are several breeds.
I would like more Bantam Cochins like the one that died, but 'they don't make them', I found once I started looking. She was a blue, but not dark, a very lovely pale smoky grey color. I know she was a blue because she moulted once, and her pin feathers came in the most amazing color of mettalic turquoise!
Why are the breeders all always sold out?
Here a photo of the murderer, craning her neck trying to be a giraff, or something. She's called Pencilled.
