I currently have 7 Rhode Island Red chicks in my brooder. They are 3 Weeks today and as a guide I'm going to post pictures of them each week and see when i can tell the Pullets from the Cockerels. I would also be happy if you could try and tell me what gender they are looking like. I know at 3 weeks it's almost impossible to tell but here are the pics. I also added my guesses to the pictures. 1) Sparky Pullet? 2) Speedy Cockerel? 3) Swifty Cockerel? 4) Sunny Pullet? 5) Spotty Pullet? 6) Sandy Cockerel? 7) Stripy Pullet? Thanks. Next Wednesday I will post more pictures.
