I know most everyone here posts in hopes that they don't have roos. I, on the other hand, kee hoping that one is going to suddenly appear in my flock. I had two great rescue roos up until August and then they vanished while I was away. I live in a rural area and they were very determined to be rovers but it still broke my heart. My girls are from a hatchery mix. They all seem pretty similar in size and development so I have no reason to think that there could be a boy lurking. But still I hope. At what point in their development would rooishness become clear? They are about 13 weeks old now.
