Hi there and welcome to BYC!
In regards to pros/cons on the breed...
They are normally a very sweet breed. The females like to go broody often (aka egg hatching mode), and many people use them instead of an incubator. They are, if anything, a great conversation starter. Let someone who has never seen a Silkie, see your bird. They ARE going to ask about it. Although they are pretty common among chicken keepers, the general public seems to have their mind blown by their looks. My neighbor calls them my Hippie Chickens.
Some people will say they are aloof, or even stupid, but I think a lot of that has to do with their crests. They simply can not see much above them, so they are an easy target for predators like hawks and other birds of prey. The good news it you can safely trim their crests so they can see better. Nothing extreme is needed, just tidy up the sides a bit so it's not hanging over their face. I can always tell when it time for a trim as one of our boys bites me when I go to pick him up (I'm guessing because I scared him). However when his crest is trimmed, he can see me coming and does not bite.
The feathered foot thing is a complete conversation of it's own. Some people love it, some hate it, and some debate if it is a beneficial or detrimental thing. My biggest con about the feet is they get dirty VERY easily. Our boys are white and their feet are too, just under the dirt.
They have black skin which is cool. They also have 5 toes which is both cool and very strange at the same time.
They are not able to fly, and that does need to be taken in to consideration. They will not be able to fly up to an average height roost. Our boys chose to sleep on the ground, and snuggle up together to stay warm. To me it's not a deal breaker, but they will either need a ramp to their roost, or a secure spot on the ground.
It's the only breed my wife likes out of the ~12 breeds we have here.
I'll let some others chime in on the incubation part, but in regards to the Silkies, I say go for it!
Best of luck!
