I know some flocks have cement bases for coops. To make clean up easier, to make the coop predator proof.
Good reasons to build on cement.
However cement holds cold for a long time radiating that through the bedding in winter. It will hold warmth conversely longer through the fall as well. I will say that I've had trouble with broken toes and such with birds landing too hard on the coop floor. Cement makes me feel that would increase those issues. Idk.
Ivie makes points about chickens digging through litter and dirt. Cement could be topped with a big fluffy layer of litter I guess.
Personally I guess I'd go with a more natural set up. One could use the cement as a patio for a bench or chairs used for chicken tv watching or to build chickenn supply storage next to the coop.
Hens can have a loud egg song or predator call. Checking with neighbors is a good idea.
Sure, you had to be contrary to me, didn't you?
I have never noticed the toes being broken. I will have to look. Time to go outside and get some stuff done, but feeling lazy and needing more coffee..
