Congrats on your new silkie babies!
I'm in a similar position as you. My four chicks are on order and set to be delivered before the end of the month. I chose this coop for them. I bought if from a store in the next town over called Rural King.
I had a small flock of 7 birds before, made my own coop and it did not work out. Lots of people suggest making your own, some will even insist it's the only way to go. I tried building my own but could never get the roof right for the run and coop. I went with aviary netting and a solid tarp all held to the frame of the coop and run with zip ties. An opossum got in anyhow and destroyed my flock.
The kit I have needs some modifications such as weather resistant paint, some sort of weather resistant sealant where the asphalt roof and wood meet, upgraded hardware, added ventilation, an extended run and some sort of platform to keep it lifted off the damp earth to help the wood last longer. I'm thinking patio stones at this point to go around the perimeter of the whole thing. I don't have any burrowing predators in my suburban backyard. If I did, I would also need a buried skirt around the perimeter. I did my best research I could, and decided that many of the coops' shipping fees made it prohibitive. I did see a very small one at Home Depot but it looked small for even two chickens, even just for night time lockup, even with the separately available run extension.
It seems the things to consider are how much time you will let your chickens out to roam around your outdoor space, what sort of predators will be in your backyard and the climate of your area. I hope that can help you narrow it down. Lots of people will tell you lots of things and even be contradictory. Just remember they're your birds and everyone enjoys their flock differently. Do the best you can with what you have and I think you will love being a chicken parent.
