I only have one. She's awesome, though! She's soft as silk, full of personality, and a relatively quiet girl. She's also a rockstar forager. She was the tiny little chickie in the brooder snatching the occasional fat beetle up that made its way through the hardware cloth and then beating its wing covers off so she could eat it while the rest of the chicks cowered in the corners.
My only hesitation about having a whole flock of them would be egg size. Hers are 47-49 grams (size small) and her frequency is not as good as my other breeds. Now, granted, she's not quite a year old yet so the eggs might get a little bit larger but I suspect she'll never pass a medium nor be an everyday layer.
