Hiya, and welcome to BYC! 
That's a staggering amount of things for anyone to go through with chickens in one year! So sorry!
Be sure if you have any other issues that you post them in our Emergency/Diseases/Injuries forum, as folks will help you out.
We just put a Cozy Coop radiant heater where a Silkie momma is taking care of the ones I hatched. She had a couple of broodies helping her, so that was fine, but when the other two left to go be broody elsewhere, that left a little silkie hen with about 40 chicks to herself.
If yours can handle the number of chicks, they shouldn't need anything else though.
We're glad you're here!
