Don't buy the coop you're thinking about--that one really only has half the livable space in the specs. I have a prefab coop and 2 years later it's falling apart and only currently housing 2 hens. I'm almost finished building a much more suitable home but this is what mine looked like when it was new: I raised it up on a 2x6 frame with a hardware cloth apron around the outside.

I purchased mine at Costco for a lot less but still a waste of money. At least I found out that I really do love having chickens and now I know it's totally worth it to build your own (when you have time). Even the "extra large" size of this one requires a lot of free-range time. I used to let them in my yard every day until they practically ruined it. A few months later the coop was moved to the whole enclosed side area of my house where they can scratch and destroy all day long to their hearts content.
Some things to remember with a prefab is you will have to ADD MORE VENTILATION (which I did do but not shown in this pic) and something I did not do... SEAL IT WITH WEATHERPROOFER! And caulk any gaps if you want it to last through winter.
With a prefab, the hens will spend all day in the run area, not the tiny coop area unless it's time to lay an egg. The roost bars cover the small floor space and there's just no room to hang out. Food and water will also probably have to go in the run, so a fully covered one would be better, especially in case it rains. Maybe this could work for you:

but bigger would be better. At least keep to something that's raised and utilizes run space underneath the coop. That one little ventilation window won't be enough. If it's too stuffy inside your hens won't go up to roost at night and maybe even start laying eggs elsewhere. Cut out giant holes in all the upper coop walls and cover with hardware cloth for ventilation. If you can let them out in your yard (or a section of yard) all day then the tiny coop space is less of a concern.
Of course, you'll have to make sure you never get more than 3 chickens
Even though these prefabs are convenient, you'll still need to make some modifications to to keep your hens healthy and safe.
sounds like a better project for when the kids are older.
It's up to you but really wasting your monies. With only 3 chicks, you could start them in a plastic bin with MHP, look for (CL) a dog kennel (chain link) not crate. Set up the kennel in the yard, put a plastic dog house in it & shade cloth over the top.
