Is my coop too small?

[Secilyd]

I’m good at chicken math, but not regular math. I bought this coop but haven’t set it up yet. After further thinking, I’m worried it’s not going to be big enough, but this is my first time having chickens. Reviews for all prefab coops seem to be so hit or miss...I get that it's not the best, but realistically is it safe/healthy? One person says don't put more then 4, another says they have 10 ducks living in here. So confusing! I live in the Midwest and was hoping for 6-7 chickens to start. We are not allowed to free range because we are in a neighborhood. We were hoping to build or get an omlet coop next year. Will this coop fit 6-7 until then? I’m open to getting a second run to put off the other side too. Also, any recommendations on “winterizing” a prefab coop like this? View attachment 4309501

No I took mine back and I have four

All things considered prefab stuff is incredibly junky.
You would do best to check around for any local shed or outdoor structure builder, even a local handyman of sorts.

I've seen prefabs basically show up as cardboard level when it should be wood. Prefabs that are sight unseen also bring risks.

Before anything, ensure you aren't planning on more chickens anytime in the future, then build to fill that maximum goal.

You can use sheds or carports, honestly anything to make a coop. Putting together a run is quite easy by comparison.
If you need to plan for snow that helps make decisions for how to setup your coop/run.
