Most of those I should have. Instead of the BCM, I hope to have plenty of Welbars around that time, and they are very sexable. The Ameraucanas are not sexable as chicks, but Silvers are sexable at 3 4 weeks. Lavenders are very hard to sex until they are several months old. The redeeming thing about them is if you end up with a roo, they are about the easiest breed/color to sell to a good home.
Someone has lavender orpington sexlinks for sell. I wonder how he gets them? I know if you have black x lavender, you will get black chickens with lavender gene. I don't know if it's gender related though.
