Hi there.
When starting out a hobby, you don't have to go full on business mode... Start small and see what your market is. Honestly, it's a HARD way to make any money... breaking even or covering your cost is good goal.
Silkies are a breed I can sell ALL day long and have a waiting list. But they are also very much a labor of love... and despite them being my best seller... I no longer keep them. Quality is key, people who are willing to pay my price aren't looking for hatchery quality birds. And I personally like bearded Silkies MUCH more than non... though both standards are accepted for showing. Chicks sold for $10 each straight run. I'm not NPIP or I would charge a little more even. And that was fro my standard black, blue, and splash. The Lavender and cuckoo went for $15 each... I JUST discovered chocolate... and those can be sex linked (as well as cuckoo). Buff as far as I know is a difficult color to keep nice... and for me, just meh... but you gotta do what YOU like.
Your Ayam and CCL will put out sex linked chicks... But they will be barnyard mixes. I think you could sell more pure CCL for higher value... what I discovered is people don't care about buying "rare" or mix breeds... but they love to buy popular breeds. Working on your own breed is a LOT of time consuming work trying to get it to breed true.
I would just stick with all Silkies and expand my colors.. not mixing them.
Beyond that... breeds that sell well (for me) are French black and blue copper Marans. Lavender Orpington seem popular... for me they were to slow growing and heavy bodied for their production to make me want to keep them. Maybe Lavender Ameraucana... Gotta do with what YOU love.
Sourland gave sound advice!
Good luck.
