From what I'm understanding this is one of the breeds that is difficult to sex. I have one and I have no clue. Most people say rooster by picture but I took it in somewhere and they said they wouldn't say rooster yet. Mine is 6 weeks. I have different breeds and the tail feathers are the same as the females, the legs are not any bigger. I can't find anything other then the comb that says it might be a rooster..do we wait. I might do a blood test to find out.
Yes wyandottes can be hard to tell sometimes. My recommendation is wait it out. Our first year we got 5 and I was worried we had three boys and two girls we ended up having 4 girls and only one boy.
I've had them a couple more times since then and they always seem to keep you guessing
