Ya if I had more property I'd have 50 of them lol if I had 8 birds with a 4x4x4 coop with a 8 x4 run do you think that would be ok if keep my 3 Plymouths and 2 black sex links and 3 couchen bantams
In my opinion that's not big enough.
I have 8 in a 3x3 coop kit from
Tractor Supply and a 6x12 dog kennel we had laying around and it's way too small. Of course the coop sits right in the middle and is partially enclosed on the bottom so the run is kind of cut off but still
The minimum is 4 square feet per bird. Some will say 2 or 3 square feet is fine but that's commercial standards mostly and it really isn't imo. I have heard some say 4 square feet is for Leghorn sized birds and for larger dual purpose breeds it should be more but I think 4 square feet for most chickens is fine.
I am currently in the process of building a new coop and run.
The coop is going to be 4x8, with a 6x8 base for nest boxes and storage. The 4x8 does not include the nest boxes.
If you have a large run or free range you might be able to get away with it but that run is tiny too.
Now you have bantams so could possibly squeeze into that coop but I don't think it would be fair and highly recommend just building a 4x8 coop or rehoming some more. We found a really good plan on here for cheap.
That 4x4 coop is 16 square feet and so could hold 4 chickens, maybe 5 if you wanted to keep just the large fowl or rehome some large fowl and some bantams. Although on another, completely separate note, sometimes the smaller more docile bantam breeds get picked on and bullied, even killed sometimes, because chickens LOVE to push their weight around so it really isn't recommended to keep bantams and LF together. Unless maybe they're feisty breeds and not Silkies or something. You should build a separate coop or rehome some.
The run is 10 square feet per bird.
Our run at 6x12, 72 square feet, is big enough for 7.2 birds. 4x8, 32 square feet, is only big enough for 3.2 birds. No where near big enough or fair. They need room to scratch and dust bathe and do chicken-y things.
Our new run is going to be a hoop coop (made with cattle panels from
TSC), a cheap option, and 8x16.
