I caught a hint that you can sex them by the colouring? Can you tell me more? I have 5 from my hatch a week or so ago (incubator trouble so only 5 of 16 made it !) I had noticed there were some differences in the colouring and some of them are a lot bigger than the others... tell me more I am dying to go and see how many pullets and roos I have! Oh PLEASE let there be at least 3 pullets!!
