Great! Thanks! Was also wondering at what age some of your roos started crowing? We kinda have a little pool going on in DD's 2nd grade classroom and was wondering if we may hear or otherwise know something by the end of the school year, May 27? The lids were fascinated with the chicks and their little mohawks. It is completely surprising to me how many kids really don't grasp the whole eggs from a chicken thing! Unfortunately I think I may have gotten a whole class of 2nd graders begging their parents for chickens! Well, thanks again!
