Oh goodness, silkie tips... where to start! I guess the first step is to decide what you want to do with them, what do you have them for, are you getting hatchery silkies or do you want SOP silkies or just fun pets but from a silkie breeder?
I have a spectrum of silkies, I have one from TSC that is a very standard hatchery quality girl, then I have nice pet silkies and a few that are quite fancy and posh

They can be quite good egg layers, mine don't like to always use the nesting box, any old corner will do. I have a few that are very active and lively, and some that are extremely ditzy and need help.
Silkies need good quality feed, they can be more prone to vitamin deficiencies. They are also more prone to poultry diseases, so even if you have large fowl now that have no issues, that doesn't mean the silkies won't. I recommend having them vaccinated for Mareks, but that is totally up to you and I encourage you to research about it! You have to keep an eye on their crests to be sure they can see, mine need eye trims every few months, check their feet feathers to be sure they aren't walking on them, most of mine I have to trim their toe nails a few times a year, they just don't scratch around enough to take care of them. Plus the 4th and 5th nails don't touch the ground anyway.
They can either be super fragile or they will be indestructible. I prefer to not have vaulted silkies, I don't want a massive crest, that doesn't fit the SOP anyway. I don't want a slumpy bonnet crest or one that impedes their vision too much, although I do have some like that.
Some areas are more prone to mites and lice, and they love silkies, so you will need to keep an eye on that. They don't always know / learn to go into their coops at night, you might have to hand tuck them in, every, single, night... make sure you have a broody breaker cage or 5, they can be super stubborn about that.
They're super cute though, so as long as you have the time and passion to accommodate their needs, they are a fun addition.
@Debbie292d exclusively has silkies and has a lot of knowledge about them. If you have any specific questions ask away!
