You need to take a course on probability and statistics. I'm serious, it could help you understand that it's just odds and how to figure those odds. I've had 7 pullets out of 7 straight run before. The odds of getting zero cockerels in seven straight run chicks is 1 in 124. That means if 124 people order 7 chicks, 1 will get nothing but cockerels and one will get nothing but pullets according to the odds. That means that 122 people will get at least one pullet. Which one will you be? No one knows.
If you get 2 chicks, 3 out of 4 times you will get at least one pullet. If you get 3 chicks your odds of getting at least one pullet go to 7 out or 8. With four chicks it's 15 out of 16. In a lot of those cases you'll get more than one pullet.
You don't get guarantees with any of this, just odds. How lucky do you feel?

I'm hoping that we don't go the straight run route, but this has been very helpful with planning for it
