Ideal has a $25 dollar minimum on all poultry they sell. If you order less than their minimum number they will put male chicks (chicken) in the box to keep the babies warm. They did it with goslings, they sent 3 goslings with 13 'free' male chicks.
ETA: Sorry, I just checked on their site. Since they don't hatch them themselves you have to meet the minimum. For the broadbreasteds and chocolates they don't have a minimum listed on their site. All others are at least 10 unless you get an assortment which have minimums of 15 (3 breeds) and 20 (4 breeds). I would call them if you are interested in broadbreasted bronze or whites or chocolates and see if they would do the $25 minimum order.
