I assume that means the extra chicks they put in to fill the box, and supposed to be roos??? I have had a few extras with orders from hatcheries the last 2 summers but they were the same breed as what I had ordered and not sexed. What I am wondering though is if their extra roo packing is of the same breed you order? I ordered self blue D'Uccles and white frizzle Cochin bantams. I expect some of the frizzles will be "curlies" (I read somewhere that is what they are called) and will have to let those go. I have ordered from Ideal this time. I know the local feed store gets at least some of theirs from Ideal (Maybe all). I have ordered from The Poultry Hatchery( A&J Farms Domani Ranch) and from Cackle before. Preferred Cackle, but I could get all of the breeds I wanted at the same time and pay shipping just 1x. help please???
