You would have to do your homework. How are they going to be shipped, as cargo on a commercial airline? Will the hold be pressurized and heated? How long is the trip, timewise? How many different legs to the journey? What happens at stops along the way; how are they handled? Will they be able to stay warm and get enough air while in the air.
Most hatcheries will not ship from Missouri to Kansas without putting 25 chicks in to keep themselves warmer. Does this breeder ship heating pads with the chicks? If so, how long do they last? If I bought chicks, I'd get the 2 dozen, if I was happy with the shipping conditions.
Have you considered buying eggs and hatching your own? You's still need to know how they are shipped and handled. I would not be satisfied with an unpressurized, unheated hold, but you might have better luck with two or three dozen eggs rather than chicks.
