Is my run okay?

[RuthhoneyEstherFrannymom]

The coop that I purchased has a 10 Ft long run connected to the coop. Is that big enough for 4 chickens? I live on a rural property and I’m a little nervous letting them free range.

Approximately 2'x12' is only 24sqf. You need double that.
Not only is the run too small, but so is the coop. No ventilation either.
