Hi! My coop is a little larger that 9 x 9 with a 10 x 20 run...I have 20 birds. I wanted to max out my coop and run
It's what us newbies do!!
Now that I've had my chickens in it for a few months I think I would have preferred maybe 12-15 chickens in it. It would stay cleaner and I do think
it's a little crowded for my taste. I put 4 nest boxes in and they usually use two...occasionally the third one. The fourth box I plan on closing
up and using it for storage.
I have two roosts at the same level that span the width of the coop, so 18ft of roosts. Plenty of roosting space, but I think I'm going to put them at
two different levels at some point.
I have a 4 x 9 service area that the nest boxes stick out into. It's great to have extra space inside for feed, shavings, grit, etc. I have room to put
a dog kennel in for an injured bird or for doing introductions.
Just sharing what's worked for me and what I'd change.
