We just got this two week old RIR to replace my 3.5 month old RIR that turned out to be a roo (we are in the process of re-homing him). I'm REALLY hoping this is a hen. In the last picture, the RIR is in the back and you can see how her tail sticks straight up - not sure if that means girl or boy (or neither). Please help.
The crest is also neither here nor there... Possibly looking more male than female though. It would help to see another of the same breed at the same age that's been kept on the same diet in the same environment from the same family... lol... And even that wouldn't guarantee anything. How helpful of me, I know.
