Hello, I recently acquired three crosses of Rhode Island Red roo over a white leghorn hen. It was a clutch of about 20 or so, some white with hardly any color, some white and brown mixed, and a few orangeish with white speckles. The guy who hatched them said the mostly-white ones were likely to be cockerels. They were 13 weeks old (when these pictures were taken) and I have a suspicion that I have at least one cockerel. Has anyone else bred RIR/WL with coloration similar to these? Do you think both the white and brown ones are cockerels, or just one or the other? I can see that the one with the fuller comb looks a bit taller/leaner, but not sure if that is due to it being a week older maybe, or its genetic individuality, etc. Thanks!
