Nancy, really?, I was also thinking if maybe a mistake could ever happen. I read a thread about a "mystery chick" so I was thinking about what if we have a boy instead of all girls.
How long does is take for a difference to be noticable enough for me to understand if any are actually baby roos?
From everything I have been reading it takes a few weeks to a few months to be sure if it's a roo or hen. Sometimes it's obvious if a comb is growing in the first few weeks or really thick legs; other times not so much. But people on BYC are quite knowledgeable and if you post good/clear pics of face and body and legs they can sometimes tell at 8 weeks or so. Considering I am still waiting on my first ever chicks to arrive in 24 days (but who's counting) I really am just telling you what I have read on here, not first hand knowledge.
But I would hold off on specifically buying roos. Chances are you may have one or 2. But that sounds lit it would be a good thing for you whereas I will have to re-home.
Enjoy the new babies
