Cackle has no minimums for males of those three breeds and minimums of 3 for females of those breeds. So you would need to order two extra chicks. They can ship the first week of February or later (as of now, of course, if enough people order these breeds, they could sell out for that hatch date).
On the other hand, these are all vent sexed rather than sex linked breeds so your odds of getting 2 RIR females (80 - 85% accuracy) and 2 Americana females (75 - 80 % accuracy) go up from about 40% to about 90%.
Actually, that is 90% chance you will get at least 4 females from the six chances at it. I need a different probability calculator to find the probability of getting at least 2 females of each of these two breeds.
Not counting the 20% chance that the male isn't accurately sexed.
