How to raise my Cornish Cross for the long term?

[Camry08]

I have a CC chick that’s a little over 2 weeks old. I got her from tractor supply because she had splayed legs and she needed help. At the time I was heavily hoping that she would turn out to be a white leghorn. But alas that is not the case.
She’s currently growing up with her two EE sisters who are a little less than a week younger than her. eventually, I want them to all live together with my two brain dead silkie boys (my boys have lived with girls before they don’t know how to mount or do most chicken things was hoping this year‘s babies could teach them how to scratch or pick at grass or something).
I guess this is my biggest question. How should I go about doing this? Feeding her and feeding the other two? At what age do I start withholding feed and is it detrimental to withhold feed when she lives with two Easter eggs? Should I just remove it for a few hours at a time?

Any help, suggestions, insight, experience all would be greatly appreciated.

Take your feed out at night when they sleep. Did you fix her splay leg yet? Is it confirmed it's a she? Cornish Cross cockerels are sometimes better off getting butchered because they get much bigger than the females.

About your silkie cockerels, are they healthy? It doesn't seem normal that they do not know how to scratch or peck at grass. It's a good idea to help them learn with the new chicks, just watch out if they try to mount them when they're still small.
