1. What needs to be on the ground in the coop? Do I need to put pine shavings?
People use all kinds of things: dirt, sand, wood shavings, wood chips, dried leaves, hay, straw, grass clippings, whatever. Some people turn the run or coop floor into a compost pile, to me that looks like a good candidate for that.
To me the main issue is how wet does it get and stay? If it drains fairly well and stays pretty dry you'll probably be OK with about anything you do. If it stays wet it will probably stink and you will need to do something. The nose test is what I use to determine if I need to do something.
2. I have 6 nesting boxes - is that enough?
Yes plenty.
3. Do Chickens need “toys”? I fear they’ll get bored!
To me the greatest boredom-breaker is room. If they have enough room they can pretty much entertain themselves and stay out of trouble. If room is tight any problems are magnified. I can't tell from the photos how many of those buildings or fenced areas they actually have access to. I can't tell physical size either. When I saw 15 chickens that was my first thought, how much room do they actually have?
You can greatly improve the quality of room you have by adding clutter. That means giving them thing to hide under, behind, or over. Yours are Silkies that can't fly so bear that in mind but most chickens really like to perch, just sit up on things and look around. It doesn't have to be that high as long as it is up some.
They also like to scratch through things looking for something to eat. That's why a compost pile in there could help. I'd give some thought to just raking leaves in there for them to scratch through.
4.Anything else I am missing or need to know?
Probably but I don't know how much you know, how much experience you have, what your goals are, or many other things so I'll just wish you good luck.
