Ok, if you don't know that movie the subject line won't make a lot of sense-- my 6 week old chicks haven't let me know yet if they're hens or roos. I think they know what revealing their sex means for them! I was depending on the farmer I bought them from being able to tell me when he delivered their coop Saturday (yay! out of the garage and into the coop!), but he said they all looked like hens except maybe 3 (this is out of 10), but then his son said exactly the opposite, maybe 3 hens the rest roos. So we decided to just keep them all until we know for sure. (The dad made me very proud when he told my husband he had never seen 6 week old chicks look so healthy and good! ) Something I have seen a couple of times in the last few days is some of them sort of "sparring" with another chick, like they're about to throw down; is that typical of either or both sexes?
