coop size

[Hooterville]

I have a lot of room to be fenced as additional space for my chickens to run safely in the spring/summer. I'm wondering just how big a coop has to be--how many chickens should 1 coop be able to support.

Mine is approx. 6 x 8. It used to be a really nice play house--with 2 levels. I took out the top level but the ladder is still in place and I put 2 more ladders crosswise for them to roost on. Nest boxes are on the opposite end from the ladders.

Tightly constructed with two windows, nice door and a storage bin along the back wall that is of no use to me now. I'm just wondering how many chickens could use this size coop comfortably. I know it depends on size etc. Right now I have 3 BAs, 2 Americaunas, 5 smallish mutts and 1 roo.

They already have a large fenced in run but I have more fencing to do so they'll end up with a nice large area for more scratching!
When finished it'll be about 50' by 150'.

What do you think of this arrangement?

You need at least 3 square foot regular size chicken and 2 square for each bantam. You could have 16 full size chickens or 24 bantams in that house. Run size is usually 6 square foot per bird

12 full size.

The norm is 4+sf per bird in the coop and 10+ in the run.

So then I'm pretty close to my limit on this coop having 10 hens and 1 roo, right?
It does stay nice and clean and it seems like there's plenty of roosting space. Maybe I've got my measurements wrong!
Thanks for the info!

Wildsky is correct. You should be fine with what you have but I, personally, wouldn't add anymore. It will help enormously with your large run, as long as they have access to it all day and are only closed up in the coop at night.

Good luck and have lots of fun adding onto their run.
