I was watching my 3 week old cots at a distance today and noticed one of them chasing another. After a few minutes I checked them and the rosetta was bleeding a little bit right above it's eye. I also noticed my pharaoh has been defeathered on his scalp. There are only 2 I can sex right now, the pharaoh(M) and the roux dilute(F), but I have a hunch 2 of the pieds are roos as well. Their set up right now is 2'x2' with 6 birds. Should I seperate them? How do I discern who goes in with who? The pharaoh and the roux dilute are friendly to eachother but should the rosetta go with them? I'm certain it was one of the 3 pieds that I saw going after the rosetta. If I seperate them how hard would it be to reintroduce them as a flock for winter once they can handle the chill outside?
