I have three 4-week-old sexed pullets and am super paranoid about chick sexing. I've seen so many people ask for advice here about sexing what was "supposed" to be a pullet but turned out to be unanimously identified as a cockerel. So, I'm just wondering - how often exactly does this happen? We live in Seattle and are not allowed to have roos. My other question is, if we did have a cockerel in the mix, what then? A duo of chicks seems kinda lonely. Would it be wise to integrate another bird into the flock? Hopefully, I'm just being paranoid, but I'd rather mentally prepare myself for the possibility of saying bye bye.
