They do, but last year, I read many tales of people buying from them and getting little boys instead! Unless you sex them by DNA, there isn't a sure fire way to do it, and you might still wind up with little cockerels.
Basel, perhaps you should just buy a couple of started birds (young adult) and go from there, it would be a lot safer if you can't have roosters.
Oops! And good point about getting a young adult. Would they still bond to me if they were older?
Thanks!
