Okay, my RIR are now about 4 days old. There are 3 of them. Using my astonishing chick-sexing superpowers I am going to predict their sexes. And in order to spread the knowledge (or folly) more widely, I am going to explain my reasoning....a monograph will soon be forthcoming.

I am basing this on three factors: Colouring. Rate of Primary Feather Development. Tail Emergence.

For those still interested in the Leg Pull Theory....they all tested as roos.

This first chick I predict is a boy because his "partridge" markings and head spot are very light and difficult to see.
