... think the coop is to small? I don't want it to be. ...By the way, they don't spend much time in the coop except at night, laying eggs, and sometimes (not very often) in bad weather. They also have a big run which I'll be extending this fall or next spring.
Lots of people here on BYC forum recommend 4 square feet per bird and that seems to be more or less agreed upon. But as you mentioned, other things need to be considered such as access to a run, how much time they spend in their coop, etc... My chickens will be spending most of their time in their coop during our Minnesota winter, so I made my coop about twice the recommended size. They have access to a nice chicken run, but they don't much want to go outside in the snow.
I think your coop will be fine with 6 chickens, but if you get hit by chicken math and end up with more chickens, then I'd look into a larger coop. If your 6 chickens get aggressive towards one another, then maybe you will have to get a bigger coop, or cut back on the number of chickens you carry forward. If your girls are doing fine, I would not worry about it. You have a nice looking coop there and I would be happy to have that in my backyard.
I put a piece of wood over one opening and held it with a screw. It will work good for tonight.
You know, sometimes it's just about getting through the day.
