How many chickens can I fit in my 16'5" by 16'5" chicken pen?

[Pullet Press]

I have 15 chickens and 2 ducks in a 16 foot 5 inch square pen. It's really the only place I can keep my chickens without them bothering my neighbors. Do I have enough space in the pen for my chickens, and if so, how many more chickens can I humanely fit in the pen. My birds don't look crowded or anything like that, but I want to get some more chickens and need to know if I can.
Thanks in advance!

You can probably fit a maximum of 25 birds in there if the housing will also hold that many.

How large is the coop?
What is in the pen?
Can you provide pictures?
I'm not a fan of the "10 sq foot minimum" rule, especially if the space is being shared with other larger bodied birds. I prefer 12-15 minimum.

Okay. I have plans for a coop that can hold 30.

How large is this coop going to be? What do your birds sleep in now?

How large is the coop? It's a smaller one, maybe 4x3 feet. I know, I know, too small. I have 5 hens and 4 smaller chickens staying in it with some 10 week chicks staying outside. I will build a bigger coop.
What is in the pen? The floor is one half packed dirt/mulch and the other half is concrete. There's a tree in the bottom middle of the pen.
Can you provide pictures? I can, but the sun is just rising, so I'll have to wait.

1: 7' square, I think. 2: 9 of them sleep in a (i think it's 3x4) prefab coop. Don't worry, they are out all day long. The other 6, 10-week olds sleep in a dog crate. I don't know how big it really is. Soon, I'll have to take them out of it before they are too big for it.

It will be well over 120 sq. ft.?

7x7=49=WAY TOO SMALL a coop for 30 birds!
I'm personally shocked that you have 9 birds in a prefab and they come out of it with both eyes and their scalps intact.

If you truly want to provide a proper home for your birds, you need to provide much more space. Unless you have a fully predator proof run attached to the coop you need to shoot for 4 sq ft per bird in the coop. That is a big coop for 30 birds.
