Hello, finally managed to get some photos from every angle which I hope will enable someone to determine that this is a roo. He disappeared for three days just as I was asking for help here, and has turned up against all the odds, very tired and hungry, thank Goodness! The first pic shows him and his sister. He is much redder in the face and his feathers are thicker. I think he has a rooster ruff and pointier feathers. Their tails are quite different too, I'd be very grateful if anyone has the time to have a look - I'd really welcome the advice. They are 15 weeks old. Thank you in advance.
