Purple White Star - new chicken breed?

Poor Lilly has been in the wars. Today we introduced the two new chickens to our other three. Despite getting up at 6.30 this morning to keep a watchful eye on them, and being around all day, Lilly sustained a bad neck injury. Poor girl had to be separated and sprayed with antiseptic - purple to stop the others being attracted to the blood. We will have to go through the whole introduction process again next weekend!
